Thanks the one. Only 4K miles?!

i'm still waiting on the part to arrive from Germany. I was hoping for it to come in this week but the SA said the shipping time can vary (with customs and what not as well).

Wow - I also have the part numbers ending in 02 and I have an identically-shaped and located crack on mine too (taking it in for warranty replacement - making sure that my SA can confirm that the new part numbers end in 03).

We need to keep this thread going to make sure no further cracking issues with the 03 revision (hopefully that extra bracing and any other changes to the 03 revision finally do the trick)!

I went to Center BMW in Van Nuys ,CA since they are family owned and have always worked with me on previous cars issues that warranty had expired. Anyways I pulled up and I mentioned the exhaust is making a strange noise at start up and at low RPMs; they knew right away what the issue was and ordered a new muffler right on the spot; they didn’t ask for proof of purchase.
Here is a pic of the crack I found:

I will upload my invoice and new can in a bit for reference.

That's good to hear. Just speculating, but maybe BMW has extended the manufacturer's warranty to well more than the number of years ago that the first MPE left the assembly line which means they are all covered for now? Or maybe all MPEs with the pre-03 versions are covered for that one defect indefinitely.

Rxpert · 08-30-2018, 07:48 AM

Is that an "04" revised part???

Here I was hoping to get the "new" 03 revision, but it looks like it's already been superseded?

Any noticeable differences between the 03 & 04 revisions???

Edit: Removed pics.

f80er · 08-30-2018, 09:14 AM

Is there a brace between the exit pipe and the muffler on the 04?? I can't see it in that pic.

damageprone · 08-30-2018, 10:05 AM

You guys are making me want to check on mine now. It's been about a year.

Yes it has 2 braces on each side. I’ll take a pic in a bit

damageprone · 08-31-2018, 12:59 PM

Just checked and my Rev 02 has been holding up for over a year now (fingers crossed)

benzoX3 · 09-01-2018, 04:50 PM

Just got my exhaust replaced under warranty due to cracking around the muffler. Took about 2 months to order from Germany, but looks like it's a rev03. It does have the extra bracing on each side to support the exhaust tips.

(Sorry for the poor pics)

Did you have to provide a receipt? Bought mines from a forum member and no cracks so far. Keeping fingers crossed.

I just got mine replaced yesterday under warranty. My previous MPE was the 02 revision -cracked at 12,000 miles. I now have the 04 revision with the extra bracing - hope that does the trick!

My MPE was port installed so I think it's associated with the VIN. I didn't have to show any receipts or anything, but I did take my car to the original dealer where I purchased the F80 from.

Hope that helps!

Exactly two years now and still OK. That could be a good thing, but can also be bad, given the fact that we have a limited warranty of 2 years. I'm probably f*.

I’m still covered under the original vehicle warranty as it was port installed....for now

Is your car out of warranty also?

Yeah, tx but the warranty differs from country to country. I live in the political center of the EU, ... and we get the absolute minimum of 2 years. Ironic?

danniexi · 09-05-2018, 08:25 PM

UPDATE

so the muffler finally came in after a month, but because the dealership was busy i wasn't able to have it installed until today. my SA did me a huge favor and got me in this morning and I was able to pick it up before closing. loaner and everything. he took care of me like no other.

the muffler is revision 04 as confirmed by the picture. the inner exhaust pipe has the braces on both the top and the bottom (hard to take a picture of the top but i can confirm it's there). hopefully this puts an end to this whole cracking issue. if it happens again in the future then id be SOL since itd be way passed warranty (even though its already been two years since installation

).

and the pictures...

part number and revision on the drivers side.

bottom of the inner exhaust with the bracing

inner exhaust which shows the bracing on top as well.

so yeah. good luck people. if your muffler needs replacing, now is the time to do it. im hoping BMW finally did their research and put a stop to the cracking after all these years.

Bubu88 · 09-13-2018, 01:59 AM

Did you notice any difference in sound / volume? Germany got stricter laws on exhaust noise emissions which means since Juli 2018 MPE and all Performance Exhausts for F3x Series are banned. There were rumors BMW will release a more silent version in august which could explain the Rev 04 just after Rev 03 has been released 2-3 months earlier

benzoX3 · 09-13-2018, 09:48 AM

Hmm that's an interesting thought. I have a rev03 and in my unscientific opinion, it seems as loud as my rev02 (both in closed and open valves mode).

The rev03 has the same added bracing as the rev04 from what I can tell from the pictures. I wonder if the changes are more internal?

it sounds the same to me but i would give it a little more time to "break in" or let the car adapt (if there really is any change). as far as i can tell, no perceptible difference.

Can anyone recommend a shop in NY or NJ that can repair the crack on an MPE? I noticed one on my friend’s car when it was on a lift. Needs to be someone who can weld Titanium. Thanks!

fabulousprofound · 10-15-2018, 03:18 PM

This used MPE was sitting at a shop I visited. The owner replaced it with an Akrapovic not knowing BMW would have warrantied as it was installed as a port accessory, which I later confirmed by quoting his VIN to my dealer. Unfortunately, the dealer won't warranty it unless physically attached on the car, and the previous owner wants nothing to do with it anymore... oh well

being the very first version, is it worth saving and getting welded, and adding bracing like what someone posted a few pages back?
