Exhaust pipe size?

geyer25 · 07-08-2013, 01:09 PM

I have a 2008 328xi and was looking to do a muffler delete. I'm wondering what size the factory piping is so I can figure out what inlet I need for my tips. Any info would be greatly appreciated.

2.5" I believe, RealOEM might be able to say for sure.

Yeah 2.5 in some places... That post res pipe is crushed in several places but if you find a round spot it is 2 1/2 inches
