Correct.

As long as you have an invoice for purchase and install from an authorized BMW dealer, your M-Performance parts will match the new vehicle full warranty or two years on the parts themselves, whichever is longest.

Well mine has finally started to split on the other side now. I could have it zipped up like the other side but I don't want to keep removing it so I will be discussing reinforcement ideas with a fabricator to see if we can tie in the outlet pipes to the thin walls better so the cracking stops. The bummer is that it is titanium so ti plate will have to be ordered

Personally waiting for a friends and family deal (hopefully one like last year pops up again, fingers crossed). I still find it blasphemous that they can charge nearly $5k for an exhaust setup (one that requires cutting of the stock exhaust system and isn't a true full exhaust setup) and that WILL crack eventually.

They need to step up and do the right thing, whether it's 1st owner or 5th. It's defective.

Just bought a 16 with 12k miles. Put the car on the lift and found this. My local dealer who I didn't buy the car from ordered one with in 2 minutes of seeing the crack. Exhaust was on the original invoice so no issues.

won't ever consider buying the MPE after reading this thread. Not spending $5K on an exhaust that will start having issues eventually. even if it's covered by warranty, not worth the hassle to me. I'll just stick with my ZCP sports exhaust

the sad news is, I live in Dubai and the dealership here told me that I am not allowed to put any other exhaust other than the MPE as it would void the warranty, not even the Akrapovic

Was the exact same reason I chose MPE over Akra 2 years ago.

Honestly if it is such a widespread issue, 2 year warranty is not the solution: BMW should call back the damn thing.

whats funny is by now, I am sure they have realized it has a design flaw with the amounts of replacements/warranty claims they have had yet they continue to sell it totally ignoring the issue.

I can walk over to the Dubai BMW Dealership right now and order one and they wouldn't have a clue about this issue. BMW should at least stop selling it for now until they have fixed the issue....

Latest..... the r/h side cracked not too long after the l/h was repaired so back to the fabricator to see if we can prevent future cracking.
My suspicion is that since the sides of the can is a much thinner gauge than the body is and the rear hangers are right in front of the exit pipes, the vibration the exhaust exhibits especially during the cold start process really stresses those two weld areas and after all the heat cycles etc they split. Could call it design error, poor craftsmanship or what have you. When the exhaust was off you can flex the exit pipes forward and back, up and down moving the side walls......I wonder if that is what gives our cars the buzz can sound, resonation in the hollow walled can. Anyway here is what we are trying.....support the pipes in the load areas (areas of failure). We looked at some flat bar ideas but this rotated tube idea looks cool so went with it and it kind of matches the current look and texture.... We thought about putting them on top but the fabricator didn't think it was needed and it looked like ass so we settled on this. Lets see how it works out.

The shop agree's...there is no reason why BMW should not step up and support their product. it is poor customer service. I love the exhaust so will continue to work with it

I just returned from an ED, have been thinking about purchasing this exhaust for a long time now, received an email from my dealer stating 10% off all BMW accessories by June 1st, my CA said he wanted my "shopping list" so he could order the MPE exhaust+tips for me. Ive just read this entire thread and now my mind has completely changed. The issue continues to be unresolved, BMW wont address it, what shall I do but to save the cash. My dealer is big on Dinan which is also fully warrantied. Something to consider anyway.

I would buy it...it is a great exhaust, damn expensive though. Just make sure it is logged in the system when they install it and keep the dealer receipt. That way they will replace it if yours fails. And check the M performance parts warranty, it differs from the car warranty. My problem is that I bought some kind of dealer car or lease trade in.... nobody will give me the straight scoop but the exhaust was installed and never recorded. Based on that BMW will not warranty it and the dealer has pushed it off on them so I get no coverage

I hope we see a revision of the MPE that has this issue sorted

Kuwait dealer told me the same thing regarding warranty.

I still bought the Akra EVO

ahh so it's not just a BMW Dubai thing! Strange how Abu Dhabi Motors are the actual dealers for Akrapovic here and will install it and cover your warranty when the Dubai dealer would void it I just don't want the hassle of having to go to Abu Dhabi everytime I want to do any warranty claims

It is unfortunate that it's happening.

With dealers replacing cracked MPE so often I'm sure BMW has looked into the issue or at least got in touch with the manufacturer of the exhaust. $5k replacement exhaust systems are surely costing someone down the line.

As long as it's under warranty I would still buy it. Simply because no other exhaust delivers the kind of acoustic experience, and piece of mind knowing it's under warranty.

despite all these posts and reports, it surprises me I still see people buying the MPE

[ApexM3]

This just happened to me on my 2016. I ordered the MPE with the car, 14k miles later i hear a super nasty rattle sounds during cold start. Took it to the dealer this morning and they confirmed the MPE is cracked.

They are replacing under warranty.

[XHH]

Same issue here!!

[f80er]

Yeah these exhausts are trash and BMW is trash for not standing behind them when they see them crack like this. Its identical on every singe one of them.

Actually I've decided to not order the MPE with my '18 order. The incidence of this issue is ridiculous. I'll stick with the standard zcp exhaust, it sounds good enough. If BMW decides to implement a fix then I'll consider it down the line.
