M3 exhaust and cold air intake
I am interested in changing out my current stock M3 exhaust and adding a cold air intake to my 2003 M3 coupe. I would be very interested in any comments, experiences (positive and negative) and product recommendations. I am new to this site and to the San Diego area. Does anyone know of a good BMW mechanic / tuner?
You would expect that but....
The E46 M3 has cats as part of the headers. Until you change to either the euro set up or supersprint you will not free up much back pressure.

Oops, wrong key: about the US or euro cat.
I was thinking euro set-up, because I'm Dutch. But with a universal cat, I think one should be able to get thru the emmisions test.
