For me....everything from the block to the tips...MSDS, optimized y, tru-bends catback, deleted cat, magnaflow straight thrus for the resonator and mufflers. That oughta do it, well, optimized the TB last weekend. And did the contour.org intake setup about a month back. (KN RU-3530 with maf adaptor).
So badly want to do some tinting, but since I have moved to ILL I have heard some real horror stories about police and tint laws.
Cant wait for SZ, I finally know a few people on the board and will be there in time for the high HP dyno runs. I got in at the very end of dyno time last year. The highest number I saw was Y2K's car I believe, the one with the venom kit on a 3L.
