F80/F82/F83 M3 and M4 (2015 - Current)
F80 BMW M3 sedan, F82 BMW M4 coupe and F83 M4 convertible forum. This 5th generation M3 and all new M4 features a 3.0 liter twin turbo engine (engine code S55) 425hp and 406lbs of torque! Heavy use of light weight materials makes this generation lighter and faster then the outgoing E9x M3.

2018 Cracked MPE Exhaust

Know it's been a common problem with MPE but damn only 6k miles!! Thankful it's warranty item. Must still be big issue because my SA was able to get the only MPE exhaust in stock in SE U.S.

Waiting to talk to tech tomorrow but they say it's heat related crack, not vibration.

I'll update

Curious, how did you find out the exhaust was cracked? Was the sound off? Did it rattle?

With the number of warranty claims for the MPE surprised that BMW NA is still selling the product. Lots of similar threads over on the Ďpost. With the ZCP exhaust safest route is catless DPís. Hopefully, the G80 will have a structurally sound MPE.
