MPE exhaust rattle FIX!

Hello Forum Fam, I have been on the e9x forum for years and the f8x forum as well new to the F87 forum but this annoying exhaust rattle drove me nuts when I heard it. WOW.

Okay down to the fix.

I jacked the car on a lift, and the main issue here is the clamp when the mpe has been installed. I looked by the canister and it was so close to the heat shield by the rear diffuser I knew something was wrong. That is the rattle my friends either that or the support bar right under the clamp.


I simply loosened the exhaust clamp holding the oem mid section to the MPE rear section.

Push the pipes closer to each other and tighten the clamp back to where it should be. ( I personally pushed the exhaust can closer as my mechanic tightened the exhaust clamp)

NO MORE COLD START RATTLE.
