550i muffler inlet outlet

FadeAway831 · 03-09-2018, 01:19 AM

Hey guys. I want to get a muffler delete, install straight pipes and add quad muffler tips for my 2013 550i m-sport. I cant seem to find the inlet and outlet measurements for the life of me. Can anyone help if I want to keep my stock m-sport bumper?

Inlet is 2.25 and outlet is how ever big you want. I put 3.5 but I also have an M5 style diffuser. Since I don't have a 550i, I'd suggest measuring the outlet and divide it by two.

so the inlets for the 535i's and the 550i's are the exact same?
