well, i originally had plans of doing an intake and cat back exhaust... i wanted to stay away from the CAI because i have one on my current car and it's a PITA to get to the filter when it's time to clean it. so i was thinking a set up like fujita SRI and a greddy evo 2 sp exhaust. but after reading about heat soak, and loss of torque, i'm thinking i might just swap out the filter in the stock box for a K&N, and do the HFP muffler. the stock intake system was designed for cool air already and must be pretty decent. what do you think?
