What is the best size ID exhaust for the SR20DE? I'm talking from headers down to muffler. I know above 2-1/2" I'll lose my low end torque. What are some of your opinions? (Please include the NOISE factor!) :rolleyes:

Does anyone have their entire exhaust setup the same size (from header to muffler)? How much difference does it make, for instance, if the headers are 1-5/8" and y-pipe is 2", and the b and muffler are 2-1/4", rather than y pipe, b pipe, and muffler inlet all the same size?

Anybody use the Iceman CAI? How does that size up against the HS?


PS - Please, people, tell me how to get an image in my profile! I went to Koolart, and I found the pic I like, but I can't get it to appear in the profile (on the left hand side of the screen, under "AF Newbie"). Please HELP!
