hey, ight i have a 325is and i did a custom exhaust several months ago. i did a Y after the cat into a 2.25 or 2 1/4 piping to a flowmaster. ight the thing is, the car sounds great. but what kinda bugs me is that every time exhaust questions or threads come up everyone does 2.5. does it matter if i went 2.25? to be honost i feel a lil more pep or better throttle response on the lower/mid rpm range. the top end still feels the same. what you guys think?
