So my friend just bought a very nice 2004 Rx8. When he got the car it was bone stock so then he put a GReddy catback and k&n drop in. He thinks his car will pull 2 lengths at the track. So i was wanting to know what you guys thought about this. My car is an auto and his is a 6 speed. I have 315 bfg's on the rear and i think he has 225s or something like that. so what do you guys think?
here is the car if anyone wanted to see.
