Bmw m performance exhaust

M3erez@gmail.com · 10-13-2021, 09:59 PM

Hey Fam hope all is well?
I bought today a used m performance exhaust on offer up and it sounds like something is broken from the inside.
I'm looking for an expert titanium welder that can fix the issue inside the exhaust for me.
any recommendation will be appreciated?
Thank you.

I live in Los Angeles area so I need somewhere around my area thanks in advance

Had the MPE on my 2018.

v1.0 of the F8X MPE were prone to cracking due to the thin titanium at the weld joints.

Many others have had similar issue.

I got the replacement (v2.0) MPE under warranty. It came with added supports.

Pretty sure you can just weld it back to fix it, but you'd have to verify. Saw one for sale a year ago i believe where the guy welded it to "OEM" form/condition.

Have the same issue. Just found out my MPE is cracking on the driver side portion of the muffler. I noticed a metallic/tinny sound and vibration coming from the exhaust, especially during cold starts. Took it to the dealer and they found the cracking. Luckily the car still has a year of factory warranty remaining, so the replacement v2.0 MPE is covered. Otherwise I was going to find a local titanium welder to fix it and add reinforcements.

I hope you knew it was cracked and got it for cheap. If not you got hosed.

On the plus side sounds like you also go the mid pipe. Usually these cracked muffler ones for stale are stand-alone and its more expense to get the mid than what you paid for muffler.
