Exhaust Question/Intake Question (Newb)
Everybody I'm new to the M world. I just got out of a tuned/bolton 335i. I now drive an 09 E90 AW M3. Is anybody running anybody running upgraded piping or x pipe with the stock mufflers? If so how does it sound and if I decided to change all the piping and leave the stock mufflers is it worth it? Also with the intakes does a drop in filter do just as much as upgrading intakes? Thanks.
