Anybody has an idea of what would be the best size for piping on the exhaust? I'm having it made because the stock one sounds like crap. By the way I am not going turbo or anything like that, just NA.
If it helps I have Injen Air Intake and Pacesetter Headers.
Thanx

since you aren't going turbo i would stick with some 2.5inch

Yes, no turbo so you should keep it under 3". Optimally, you want variable diameter piping to coincide with alternating exhaust gas pulses, but a safe generalized bet is 2.5" or 2.75". These guys can give you awesome exhaust tuning device:
