it's only a few samples with manufacturing defects, not a wide spread epidemic affecting all exhausts.

yes, for the money, this system might be expensive for some people, but the fitment, warranty, and most importantly, sound is definitely worth the price.

this exhaust new is around $5K+, maybe $4500 after discounts if you look carefully around the internet. the used prices have been falling and this one listed at $3400 with tips is a damn good price. it was only a few months ago that you couldn't even find one for sale, let alone at a reasonable cost like this one.

Nope, it's not... Why it is worth over 5K for a cat back exhaust? Because of the BMW Performance Decal on the can?

You can get a full system with warranty and best fitment for less than 4K, and those exhaust don't ckrack after couple thousand miles...


MPE is nice when you lease a new car, that may make sence.

Again, the value is subjective to a prospective owner. To some it may not be worth it, and to others, it is worth the price. Personally, I think the MPE is the best sound exhaust on this platform compared to other exhausts that cost the same, and some that cost more (ahem akrapovic). And what I meant in terms of warranty is that because it's an OEM piece and not aftermarket, you wouldn't be voiding your powertrain warranty as well. To each their own.

Epidemic? Come on man, its a problem, how widespread who knows but more than enough for anyone to be weary of buying secondhand knowing full well they are SOL if it cracks. @te37 bought a used cracked one, tell us did BMW warranty it for you?

Aftermarket exhaust voids the powertrain warranty?!

my point is that we don't know if it's wide spread or not. there have been only a few incidences that have been posted on the forums (literally just one thread), and clearly not enough evidence for people to get worried. it could simply be an isolated issue considering how many of these exhausts have been sold to the public. the FUD is absolutely ridiculous without any sort of substantial evidence that proves otherwise.

And yes, any aftermarket part has the potential of voiding a warranty. The likelihood of that happening is slim to none, but it is still possible.

This MPE sale reminds me of that old energy stock called Enrod...Pretty soon he, the poor OP, won't be able to throw the muffler away due to radiation contamination. However, a buyer or two here will take the muffler in for free, if the OP pays shipping.

All kidding aside, I'll be racing to my M3 tomorrow morning with a flash light and magnifying glass to check out my can man

I think this thread has been very informative... and I, like many other forum members will do after reading,..Check their MPE can man. However, I firmly believe this to be an anomaly.

Thanks Jeff I'm trying. Dropped car back off at Classic BMW today for them to try again. When I inquired about getting a regional reps info for BMW the CA that I work with offered to try and take it up the ladder further. I told him I wasn't looking to throw him under the bus or anything, my gripe isn't with him. He said they won't help with this because I can't produce a receipt. I said bottom line is the car isn't even on the road full 2 calendar years yet even. The exhaust is less than two years old and is obviously a BMW OEM part. I did mention this thread and even showed it to him and some of the responses. This is a known defect and many are being replaced. I understand I have no receipt but it's a technicality to me from my perspective. Car has less than 14k on it and honestly is a garage queen, is not driven often. CA said talking to reps and moving up the ladder is his job and I think he was nervous about me saying something bad about his service so he offered to try again, harder this time I guess So we've come full circle now to dropped the car off today and he's going to see what he can do. Told him I'm not picking it up until it has a new MPE on it just busting his balls. He's actually a nice kid and I've spent a fortune in service for my wife's 335i at this dealership so I've "earned" it I think. I always go with their recommended service and they have been good to me with out of warranty items before so I'm not going to knock the dealership or the CA. This is a smaller BMW dealership so I'm sure they don't have the pull of larger dealerships around the nation but enthusiasts especially need help when there is a problem. We are a big part of driving the marque forward figuratively and literally no?

I didn't read through the thread so this may have been mentioned, but cracking is a known issue with welding titanium. It is prone to hydrogen embrittlement that are common crack initiation sights as a result of the housing flexing.

The E9X M3 MPE was made of Inconel, maybe the source of the confusion. Inconel is much stronger and more resistant to heat than stainless steel, which allows to reduce wall thickness hence lower weight.

Just remember no receipt = no reimbursement from BMWNA. So the dealer has to decide if they want to eat approx $4k to make you happy.

I suspect a previous owner bought it cheap because it was dropped at some point.


Is the car CPO? Does this fall under CPO warranty?

So, if there are cracks to be found later, does anyone know how the warranty would work if you bought this used?

Well it finally caught up with me also....just spotted this last night. I did an inspection on Nov 2nd and all was well so it started sometime after that. I have noticed since it go colder that the exhaust was vibrating & resonating more. Mine is an early build car so it has a good 10-14k+ on the exhaust. Time to call the dealer
I purchased my M4 2nd hand with the exhaust so not sure how deep the pool will be for me to swim in. I wonder if they can investigate and tell if it was port installed or installed at dealer upon delivery since mine was a dealer car. If I recall correctly you could not order it with the MPE at the time from the factory and the only receipt i will have is for the car of course

Are you kidding? One thing to is to buy something that has got 60,000 miles on it and who knows what else on it and assume liability on that.

What we are seeing here is quite obviously a DESIGN/MANUFACTURING DEFECT. All crack propogations we are seeing are similar indicating an obvious issue with the weldment / a stress concentration at that area.
