Fitted a GPR Titanium exhaust to the K1300 GT yesterday.
I'm chuffed with it - a much nicer sound but not droning and booming and likely to be a problem on a long trip.
Just what I wanted and much cheaper than an Akro.
Very happy. ;D

I agree with you Dave, very nice sound.
-
Great exhaust the GRP, I have used them for some years now with no problems, good price and excellent quality not like most of the after market exhaust manufacturers that have been ripping bikers off for years, my last one for the 1200GS cost only £260.
-
I fitted a GPR Furore in ceramic black aluminium to the wee Honda last week. I'll have to stop calling it wee now because it doesn't go weeeeee anymore but it is still only a 250.
I was umming and ahhing between the Italian GPR and Bitish made Delkevic.
The GPR was £289 for the silencer only whereas I could have had a complete stainless system from Delkevic for £250. In the end, the Italian won out but they had none in stock so mine was made just for me and arrived with my name on the swingtag which was a nice touch. Pity it took 3 weeks to walk it up from Italy but the results were excellent.
No Cat compared to two, three-way cats in the OEM one and according to my kitchen scales the silencer weighed in at 2kgs and the link pipe and fittings took it to 2.5 whereas the stock boat-anchor was all of 5.2kgs and the Honda wears it much higher up than the K.
Being a straight through, free-flow jobbie, the GPR also freed up the breathing on the Honda and it is much livelier now than it was before.
As you said, quite a fruity note and much sportier to boot.
-
Only thing i'm not keen on with these is the hanger. Am looking at them for the GS now though, and even with the hanger issue, can't complain at ~£280 for that Furore! I'm sure I could make something fancy for the hanger... or forget about it and just ride.
Damn it I'm supposed to be saving money!
-
WTF?
A hanger is in a hangar! What sort of hamburger d'you want.
If you want a 'dedicated' hanger, pay the man and get an Akra.
If you want a GPR or a Delkovic quit yer bellyachin and get a silencer wiv a strap and a hanger...
£1,000 for a dedicated hanger...
£250 for a strap...
Get over y'sel man 8)
I didn't hear this moanin wiv yer SC Projek, innit :)
-
Hahaha :D
Yes yes i know. But the SC had a matching carbon fibre harness! I know it's not that big a deal dear ;).
Wouldn't mind a hamburger though please.
-
I made a boo-boo. :-[ :-[
Uploaded incomplete video.
Here's the correct version with all the parts of the install included.

Watching properly now!
2:28 your sound has gone tin-tinny-tin-tin by the way. Gosh, they wrap the bits up nice don't they! Sound back to normal at 4:00 :)
Aah so the rubber bit is just to prevent scratching the can then. Probably obvious but your video makes it easy to see.
Looks lovely on the bike, much neater. Jolly good! Post pay-day I shall order one. Then I need to see about those servo eliminator things for the quiet-flap.
-
Bloody hooligan Matt...
-
Don't worry, this thing has about 8km of catalytic honeycomb goodness in its intestines so it'll never be half as loud as the K with SC-Project :). And by half as loud I don't mean literally 1dB less :P
-
I've just had a look at these on ebay, £280 for GPR Furore Nero, which looks very nice, however I really want one now for their write up
"GPR are hand made in their own Milan based factory. Do not let the very reasonable price put you off. If you feel you would like to pay twice as much for something you cannot pronounce and is on every other bike then this is not for you. If however you would like a good quality exhaust at a reasonable price supplied by a trusted UK seller on the end of a phone and also show some individualism, then this is very much for you"
Viva la difference.
Love it :)
-
Sounds nice doesn't it! And another Italian factory to visit/peer at then ride off.
-

Experimenting with new microphone and new camera (Canon M50). I'm not the best with these things, but I dare say I'll get the hang of it in the end :-[.
-
The nice gent at Moto-legends where I got the exhaust has pointed out a few things:
1. The bags are apparently for you to put your crash hat and old exhaust in.
2. The end of the exhaust is not plastic but an aluminium alloy called ergal, painted in ceramic paint.
3. There is a removable db killer.
I have modified the video once more.
https://youtu.be/HbhRb9ipxCg
Price of the exhaust was £379.
Here's their full range. I believe they are still doing free delivery at the moment.

Phew that's what I thought. Moto-Legends need to stick to what they are great at!
Oh I see what you mean, I just ordered (hurrah) and the receipt stuff is moto legends distribution in Notts. Bah, still not the real ones I think.

2kg in the whatever coated steel stuff. And the old 5kg one:
OK I can't get it right on phone but anyway yes. First impressions are the noise valve is finally feeling like it is worthwhile. General pootering and it's same as usual, mid to wide openings and it blaps away with more 'character'. Tunnels are fun again. Quality was all nice, and I used the GPR pipe clampy section and retired the already rubbish looking BMW one. Will be interesting to see how it ages. The BMW bolt was even bent slightly! I wonder if someone went over 22Nm.
-
Welcome to the GPR club. Maybe we need a new forum...
-
Going through a tunnel it reminded me of I think Tom's (or Bob's) KTM on our 2018 trip, which properly roared at times. So I am very pleased :). Though it's also slightly reminiscent of the R Nine T version of the 1200 engine now too, little ww2 fighter'ee sound hah. I then treated the bike to a bit of ACF50 seeing as winter begins tomorrow.
Then Rae you will be pleased, wax oiled the ply panels.
-
I knew you would make the right decision in the end Matt :D
As you know I have been working with wood for many years and it always delights when the finish goes on and the grain pops out.
-
Yes I love that stage too. The amateur laminated work surface I made, was only pine but once I'd got the finish on, in my opinion it looks flipping lovely
-
Looks good matt. Black is cool.
I'm getting some occasional pops and backfire's on the K1300GT.
No personal comments please. :-[
-
Cheers. Yeah I think it's a tad loud/rude without the baffle. So come next Wednesday it goes back in :)
-
Well.
(https://i.imgur.com/EsXTnWw_d.jpg)
And I'm not a commuter since owning this bike.
Edit: sorry res is pants ill migrate to whatever it is we supposed to use when at pc.
-
I did say that the finish is nowhere near as good as an Akra or the OE. Mine is black also and the paint was rubbed off on the rear pointy tip when I took it out of its lovely 'protective' bag.
-
Yup I think it was the last trip out a week or so ago. Must have been grit as before I cleaned it today I noticed several spots of precipitation in the same areas. By grit I mean salt of course.
Still. I thought it would survive a bit of that. My... Whatever that noisy bugger other Italian exhaust... The SC Project, that survived fine through years of on and off use with commuting. So I can't believe all Italians haven't heard of our use for salt.
I suppose it gives me an excuse to see what another one sounds like when I get money again.
-
Well I emailed the people at https://www.gpr-motorcycle-exhausts.co.uk/ (https://www.gpr-motorcycle-exhausts.co.uk/) otherwise known as Moto-Legends (not the great clothing shop) with massive Samsung Galaxy S10 camera photos of my poor exhaust.
23rd Jan: Mail sent with photos and nice words and "I hope you can help".
26th Jan: A guy replies asking for "some bigger pics please Matt" [assuming he didn't know how to download attachments]
26th Jan: I reply nicely after taking two more photos and added them inline, full horror size 4032x1908.
...
4th Feb: I chase up asking for some help.
9th Feb: I chase up again via their online form, which says it goes to the same address.
So far, so disappointing.
@chriscanning, you're connected to everyone, can you fix this please? :winkthumbs:

i have the supplied acro and one of my riding buddies has the gpr, both k13s.
i think mine is nicer and sounds better and he says the same... i.e those are the exact same words he uses.
they both do what we wanted them to do and i have no real preference apart from the acro being factory supplied so to speak.
pity about that paint flaking but if you get no joy a coat or two of high temperature satin black will leave it in good shape again.
-

Yeah, but you shouldn't have to. For what I paid for the GPR silencer for my little Honda, I could have bought an entire, British made, Delcovic stainless steel 'system', header and all. But, the original was black and I wanted a black one and Delcovic didn't even have a plain ss in stock.
As I said before, the 'paint' finish was worn off the tip of my end cone when I took it out of the protective bag so I wasn't too impressed with the quality standard of the finish.
-
Yeah it'll be like putting mascara over the pox scars, it'll still be discernable there unless I switch analogies and sand down everything around the circle of plasterboard I fixed into the whole the plasterer left.
No response yet, it's quite odd, being 2021 and all. Next I think is a review on the Google maps result which should prompt someone... In about 8 years when they turn their BBC Micro on again.

Hmmm now there’s a challenge, cannot see as the OE suppliers are going to have an answer as all they’ll supply is another flimsy Italian outer case or complete pipe and you’ll be back to square one before you know, the home work comes in stripping it sourcing same as rivets and do you go a paint finish or anodised.
Of course if you want to go the nuclear route....contact MCN and complain, of course ultimately you’ll just end up with another crap finished end can.
-
Or a refund perhaps? Good point re MCN too thanks :). They do different finish materials I think also, so that could be an option...
-
A refund :o best of luck.
-
Fair point, they aren't John Lewis!
Their website says, re "how long is my guarantee" item in FAQ:
There is a minimum guarantee of 24 months. Proof of purchase is required. If there are clear manufacturing faults and you are the original owner we will repair or replace your GPR exhaust for as long as you keep it.
So, either straight replacement and sell it to somehow who doesn't ride their bike outside, or blag a cf one and see what problems that brings.
EDIT: If they ever respond. Maybe they're going out of business and so a bit busy.
-
It’s OK you pointing the finger at the seller....i’d Be pointing the finger at you for buying tat and then complaining.
I’ve had a good look at the photos and that pipe and the rest of the bike has seen some weather...Akra quality costs Akra money...
-
Fancy, using a bike in "weather", disgraceful ::)
-
Haha :D
Well I bought a similarly priced SC Project and it lived fine in actual commuting for several years (and also living outside for several, undercover). As I said in my words above this hasn't been used for commuting, it is the apocalypse, and this one has seen about 500 miles use. I agree that it has seen "some weather" because some weather is anything in an atmosphere. And then it has sat in a humidity controlled garage. So to be sure, I am pointing the finger at the seller/manufacturer, but I didn't buy a knock-off Chinese thing from eBay for 50 quid and then get upset when it set fire to my family. Is this unreasonable?
But hey, it's 2021 and the age of judgement so ok :P. Or the age of sentences that don't say anything. I'm a fan of those too. I've had a look in the oven and my food has seen some heat. Do you think it's ready? It's a Beko oven if that helps :/
-
Bear in mind that a) I bought one from the same outfit and b) I buy a lot of Chinese tat off fleabay.
Being an island, there is an awful lot to be said for buying UK made tat because then you can sling it in the back of the car and go and have a nice word with guys who made it assuming the guys who sold it don't come good.
Or, you (and I) could have bought it off Amazon...
Just saying and bear in mind my caveats at a) and b) above.
-
:) :) :) :) You can can dance around your handbags as much as you like... who the hell buys a painted end can where it’s always going to getting a kicking..out of 6 bikes i’ve Got two carbon(Akra) and the other 4 are stainless, its not even down to ‘Like’ just down to what wears well.
Hey you never know strip the paint off before the stones do and have polished up,might be something decent under there, or as I said before or get the body anodised...hardly rocket science taking it apart.

Sorry Chris, I think my last post must not be displaying properly as you seem under the impression it's had a kicking or a hard life. I've done about 500 miles with it. Whilst having you strapped to the side of my bike for that for could be considered a kicking or a hard life indeed, I don't think it counts in this case.
And to borrow your needlessly insulting approach to posts:
Who the hell replies ignoring the facts and being needlessly insulting?
-
:) :) :)

Matt
What do you expect?
If you are under 25 and just starting out in life and learning the hard way...then i’ll Take it all back, but after a certain... Blimey... i’ve Been there just like everyone else and if I never listened too my old man about anything else...Buy good Buy once.
You only have to see what quality exhaust cost, now of course one could assume quality exhaust people are ripping us off, but i’ve Never had a good’un thats a dud, and yes i’ve Bought plenty of crap in my time...hence my current approach...I think the modern expression is...Evolution :)
Judging by how many have already had the Covid, youth is not a common product on here so Age is no excuse ;D
-
I don't expect it to fail in 500 miles! Sheesh kebab Chris. I get you're saying it's a finish you think is not durable. But we're not here talking about a 10k miles failure, we're not talking about an intrinsic problem with this type of finish. We're talking about a failure in 500 miles! It's a failure of this specific physical item.
Now if you're telling me everyone making a black alloy exhaust accepts that they'll fail in this kind of mileage... Well patently that's not how a business would work. They'd refuse to put a warranty on it for one.
It feels like you're telling me I should know not to buy black exhausts like I know not to walk in the middle of the road. Which is all fine and good in our areas of experience and expertise. Firstly I've had akra and sc, and wanted to try something new.
Secondly everyone has their own area of expertise and experience, but there's nicer ways of sharing that than "who the hell does x?" I know if you build an integration layer using xml based Web services you're a {edited swear out here} silly sausage in my opinion, but I'd approach it as a nice human instead. And I never know, maybe they're just integrating a PoS to a basic insights platform, their traffic is low and really it isn't that big a deal.
-
Now now Matt I'm sure you can express yourself without resorting to profanities ;)
-
Sorry Rae you're right :p. Editing shortly ;)
I feel we need two thread
1. My exhaust failed in 500 miles
2. Should I ever buy a sub 400 quid black exhaust?
We've somehow got more into the second theory item when I'm concerned with the first actual reality item.
-
Oh bl8mey don’t delete the profanity ;D ;D thought was great...
But failure.. cuz the paint has come off...blimey
-
Haha you read that bit carefully enough :p.
I mean "my exhaust finish failed" :p. I won't edit that so my heinous crime stands for all to see.
-
it seems fairly straightforward to me, the finish on the can was not fit for purpose.
they should stand over it, will they? thats the question.
if we only bought stuff from established manufacturers there would be little point anyone starting up a new business (jeeze i still can't spell business). an exhaust for a motorcycle should be fit for years in the outdoors....if not they should put that on the advertising thingy even if they use small letters. my mates gpr looks good after approx 2 years, it's carbon fibre (possibly effect).
anywho, worst case scenario it can be sorted with proper paint although the polishing is a good idea but it may need to be stainless steel to last,
-
I could find no adverse comments about GPR silencers when I researched my buy last year.
Everything I read was positive, especially about the weight saving, which I wanted, and the exhaust note which wasn't offensive but was fruity. The little bike certainly performs better for the free-flowing design.
How else do you make buying decisions? The most expensive is a) not always the best and b) not always affordable, especially as not everyone is intending to keep their bikes till hell freezes over.
If 3 years is the average ownership time then the finish on ANYTHING to do with motorcycling from a reputable european manufacturer should last at least that long.
And the importer, set up especially to import and sell GPR kit, should have a better response.
I was a little miffed when they took my order, banked the money and then told me there were none in country and none in Italy either. Had I known I might have bought the Delcovic but decided to wait while they made one for me.
It 'looks' like the metal wasn't degreased properly prior to painting and while it might fulfill its purpose as a silencer it sure isn't built to the design spec.
-
How else does one make buying decision...
I run a ‘MIVV’ on my X/R, a ‘Wings’ on my KTMGT and a ‘Remus’ on my Triumph Tiger 955, The K and the XT have Akra Carbon, my old 1100s has a custom system but along the lines of the others.
The only one that involved some investigation was the Wings one as I like the look of it but never heard of them, and that was interesting.
Buying an end can with paint on it, jeez I have difficulty writing it down cuz it’s not a thought pattern i’ve Ever had, and i’m Being factual not sarcastic...heat and paint are a bloody bad combo.
-
One wonders if the finish has come off Matt's wood burning stove in a few hundred logs. The finish hasn't come off mine, nor off the stainless steel sectional flue. The paint never came off my AGA in thirty hears of use except where previous owners had dropped things on the finish.
Sperex used to last two seasons on the headers on my rally cars and it NEVER flaked or 'spotted' unless it had been put on by an idiot. There are plenty of reliable finishes out there for high temperature use and I would expect a silencer manufacturer to use them.
See Chris, either you are a genius and Matt is an idiot or you have been very lucky and Matt hasn't. But you come across as thinking it is the former.
And even if you do think it, knock it off. We've been here before...
-
Judging by the photos Matt, it does look like fish eyes which is caused by contamination before paint. If they don't admit that, it's very shoddy customer service.
-
Just for the record the Wings guy is ex Akrapovic and blimey you can tell.
-
Being a person who likes to get value for money I will investigate and get what suits my budget. As much as I would like the "top of the range newest best superest" thing on the market it is dictated by my actual fiscal availibility. The GPR looks to have failed and is a product of poor workmanship in this instance.
Painted exhausts can survive perfectly well. My SP Engineering one did three years of All Weather commuting, salted roads and so on and still looked brand new when cleaned up. It racked up around 15K of abuse and was sold still on the bike last year looking perfect (and sounding good too!).
My current brand new Delkevic Stainless steel exhaust has seen weather and salt already because I ride the bike. A bit of AutoSol and soft cloth and it is brand new again.
GPR should replace defective item with a properly coated exhaust with humble apologies.

I should think it suffice to say that most do offer prayers of one form or another on ride outs of any kind! That is the inherent nature of motorcycling with all the joys of interacting with other traffic, road and weather conditions. Theology and doctrine can take a back seat and allow for enjoyment of the ride and various forms of sustenance to be enjoyed at the suitable intervals. ;) :winkthumbs:
-
There’s some pretty deep thinking involved in yer post and i’m Certainly not going to try and get involved in that.
Trying to get back too end cans and money...I/we bought house 30 odd years ago, we knocked most of it down and built what we wanted, the end game resulted in having 50 quid between us an oblivion and I didn’t like it.... and spent the next 25 years digging ourselves out of a financial hole, too the point our income is just good as when we were both working all those years ago, and my other half still doesn’t draw a pension of any sort she just stopped working.
After my long pre amble...I realise it’s very shallow but my mental karma is helped by the bottom line of the bank account among other things, and from experience I buy the best end cans I can, although in fairness they are not always available.
Top of the list by a small margin is the Wings, followed by the Akra option and I include the packing , not too far behind is the MIVV and Remus, but in fairness their catalogue is not all that large.
-
Chris, I liken your life story to the story of most of us. We spend when we are young and we may regret what we spent much, much later in life and set about rectifying the situation.
Most folks either think their current home is 'the one for life' or they think it is a 'do'er-upper' to be flogged on as we move up.
If it is your forever home, you may be wise enough to spend the most you can afford so you don't have to do it over later in life.
If it is a do'er-upper then you might buy from B&Q, enjoy it while you have it and hope the next buyers don't spot the quality.
So with bikes. If I thought for one moment that any of my current bikes were a do'er-upper then they wouldn't be worth much by now. I always think my new bike is the big keeper and I currently have three keepers.
At my age, keepers probably means keepers. When I was in my thirties, keepers probably meant 'till I was forty'... :)
I think one's buying decisions move as your life moves and just like your home, your bikes are not bought to sell on in the next three years. If I were earning now what I was earning in my middle years, but with my current, minimal outgoings, I would have a few keepeers but would be buying 'ride 'em like you stole 'ems' two or three times a year.
Such is life. And finances 8)

I'm most disappointed nobody moaned at my millennial approach of emailing, by the way. That was the one valid complaint!
So to preempt that argument I rang them today. And of course it was down to small-business leaky processes. They had forwarded my details on to the mothership in Italy, but no response from Italy and no sad-path process to check anywhere. Anyway, he tried again and Italy have said:
Sì, sembra che abbia visto un po 'di atmosfera. Ma è anche chiaramente un trattamento difettoso, quindi dopo aver controllato un po 'lo chiederemo indietro e gli daremo un nuovo trattamento ceramico. p.s. Testa di gatto.
And the guy at the uk distributor mentioned:
Chan fhaca mi a-riamh an seòrsa fà illigeadh sin. Tha sinn air beagan fhaicinn ach tha iad air a bhith a ’crathadh nach spotan. A rèir coltais bidh sinn a ’dèanamh ar dùsgadh fhèin airson beagan bhaidhsagalan, agus tha à ite againn sìos ann an Oxford a bhios a’ dèanamh a ’chòmhdach ceirmeach. Bidh iad ga dhèanamh airson Ferraris agus an leithid cuideachd.
So that gave me confidence anyway.
-
I almost understood the second part, but my Scotish Gaeilic isn't as good as my Irish Gealic. Pretty similar through.
I presume the Italians are calling you a cat head as a term of affection. ;D

Yeah I've taken to mimicking that American lawyer fellow but I refuse to deny i'm a cat. It tricks some people. :D
-
sketchy translation...:
they haven't seen this problem before, some rippling (maybe) but not what you have. they do some for their own bikes and use a place in oxford that makes their ceramic cover (i translated the ceramic bit!). they also do it for ferraris and such as well.
i don't know if thats an offer to sort it or not but goes into detail about where they get theirs done so might be worth another wee push.
i have a few irish speaking neighbours ( i haven't really mastered english yet) so any more of that stuff i can probably get a rough translation for you.
i really don't know why they mentioned ferrari, just bumming a bit i guess, anyhow i'm away for a run the the oul zonda.
-
Haha sorry yeah, he hadn't seen that particular pattern before. But accepted it ain't right. Contacted Italy. Italy said OK send it. Then today mentioned "it looks like gravel rash." Being an absurd suggestion I noted gravel rash has a direction.
So now it's awaiting pickup.
The Ferrari point was a bit weird. But maybe he'd read this thread and was trying to assure me that this ceramic coating is actually OK.
-
If you ride VERY slowly Matt (call me, I'll explain what that actually means) then the salt that wasn't even on the road when your spotting appeared might land on the top of your can. Or if you poured some of your salted caramel malt extract special brew all over it...
Get a new one...
-
On a related note, what compound are we using if any between exhaust and link pipe?
-
I don't think there is any compound on BMWs Matt, don't they go the ball and cup route?
-
I don't think there is any compound on BMWs Matt, don't they go the ball and cup route?
That's my understanding too.
-
sounds good so far, did a little work with a r and d outfit once...loved it. they got very excited when things went wrong, you learn much more when a run goes wrong was the cry, and this i think is the lesson here. gpr supplied a below standard exhaust, i agree with rae that it looks like fisheye, and now they're going to sort it.
of course it shouldn't have happened but it did and they're doing the right thing.
as for compound, well pretty much anything will do, i've gone from gun gum to isopon and things inbetween, but in a ball cup joint a smear of silicon will keep everything tight. it may not even need anything.
once in a panic the night before mot i even used fire cement as a last resort on a golf ... that was a one off though.
-
Thanks chaps. That's good, every time I fit an exhaust I eye whatever tubes I have around, you know, copperslip, toothpaste, sun dried tomato puree, and can't help but wonder.
Agree farmer! It makes it that much more rewarding when you figure it out and fix it!
Here's a closeup. The fisheye catering concept (I briefly googled) seems apt:

I just got my old SC Project out of the shed to see why exhausts aren't interchangeable. The link pipe aaaalmost fits into the exhaust!
If I were to somehow make it fit (I.e waste a Sunday sanding the inside of the pipe end) is there a reason why it would be a bad idea?
-
that's what i would do....spend all day sunday sanding, spend all day monday wondering why...
(it's easier to get some form of exhaust flange taper and beat it up the pipe to widen it)
-
Hah :D
Yeah, was searching for something like that and so far failed.
I did get the calipers on the GRP link pipe and found it's not precisely describing a fixed radius circle. But maybe that's normal with tolerances etc. It's only about 0.5mm off.
-
silicone or gun gum or the like would probably sort out 1mm or less play, you're supposed to leave it overnight but "ain't nobody got time for that"
just don't rev the head of her until it gets a chance to set.
-
also to take up a bit of play a coke tin/biscuit tin will act as a useful spacer as long as you can clamp it.
you can cut it with scissors... not in front of the wife...and bend it nicely to shape.
-
I getchya.
Well, the problem is the link GPR pipe is slightly too big to fit the SC-Project silencer. I don't fancy doing any permanent change to the link pipe, so think i'm stumped.
-
well the coke tin idea should still work albeit the wrong way round but as it's temporary i shouldn't worry.
a nice snug fit ,a clamp and that should work, all easily removable. for a short term job like that i probably wouldn't bother with any compound or at least very little if you get a blow by.
-
Ah you mean like a collar between the two? Hm! But I will insist on using local brewery cans as Coke can go to hell! :P
-
other brands are available...
hate getting caught up in the whole pepsi v coca cola war.....

They can both go to hell :P

Yeah, you'll wake me up in the mornings if you go out on the bike...

Gravel rash me a*se, that fisheye effect is pure bad prep before the coating went on. either spots of grease still left on the surface of the steel or degreaser was not washed off fully. Oval cans are made round then squashed so top & bottom of the oval gets the most distortion which is why the coating popped there.
-
Well, Italy have said:
these are scratched due to gravel or pebbles. The body of the silencer is full of craters in the middle of the scratch.

I somewhat expected this, given I gave them the exhaust without paying a scientist 500 euros to examine it first. I'm not saying they're being disingenuous, rather a misdiagnosis.
The chap at the reseller is being decent enough and going back to them to discuss but it seems to me like they're going to stick to that story. Reseller's best guess is something mental has landed on it from the road. Like chemicals. So I suppose i'm lucky my leg hasn't disintegrated due to the same.

I think it may be time to cut your losses here Matt. Put it down to experience and don't buy their products again and tell anybody that will listen how bad they are, also put it all over social media.

Starting to think the same Rae. I don't particularly want it back as-is and I'm not paying for them to re-coat without some kind of "oh yeah we left a cat in the factory overnight, and it was a boy cat and it weed everywhere to mark its territory, so that's probably it." Which is doubtful.
-
i'd take it home and get someone to paint it... will need well cleaned as i still think thats fisheye, and as said before it's bad preparation or water in the system.
big -1 to gpr and indeed whoever you bought it of... they should at least be offering you a deal on something ...at the very least.
get them named and shamed.

YouTube it. Do a wonderful video and you can also tell 'em about the paint being worn off the end of mine in transit, even though it was in there lovely protective bag.
