My question: What size exhaust? 2.25", 2.5" or 3", in terms or value for the buck, for this setup? I plan to get my muffler shop to custom make one, no name brands, WITH cat (no test pipe). I race only ocassionally, and dont drive hard during regular commute, if that helps.

well a 2.5 would be ok, but if you plan on modding it more i would go for the 3", i would be better for the long run, but then you have to get a 3" cat or a 3" high flow cat of ebay for under $100.
