alright then what's the real size of the evo exhaust .. first gen? i hear either 2.25, 2.36 or 2.5? reason i ask is because if the downpipe is 2.5 then a 3" exhaust wouldnt really make that much of a difference would it? i dont' know it just seems like logical thinking

makes sense, i have wondered that myself, but 3in pipes have proven to make more power...add in a test pipe and gain another 10-15WHP on top of that....i think there is more to it though.
