Hi I have put a Greddy EVO TT exhaust on my EP3 civic type R. I know it was designed for turbo or supercharged CTRs running 300BHP+ because of the bore size but I really like the sound so i'm using it on my relatively standard CTR with only this exhaust system and a tegiwa induction kit (cold air with proven gains realistically around 8 BHP) My car might be running around 210 BHP without being remapped, so far it doesnt feel any slower with my new greddy exhaust (the previous OEM pipe was only 2" bore compared to this 3") but as i've read that whilst it can increase BHP and high RPM this can be at the expense of low down torque. How much toque are we talking about and does anyone see this as being a problem?
cheers
