The show "gearz" did a bit on exhaust sizes, you could probably find it on a search through YouTube. He tells you the propor width piping for your power output and setup.

IMO I'd go with a 2 1/4 or 2 1/2 straight pipe catback with headers if u got them. If u have a cel delete or whatever. I don't like the check engine light on so I'm currently running a cutback behind the sensor straight pipe. Best breathing IMO and cause I still have pre cats an cat it's not annoying loud. Sounds like a deeper m3 from what I got. 328i intake and alittle other things. Sc will b in soon
