I have always gone with one 2 1/4 and it has never done me wrong. I will never go higer than 2 1/4 until extreme turbo times
Stick with one 2.25" pipe. Cars that are designed with dual exhaust need dual exhaust, but cars that have a single exhaust are designed to have single exhaust. If you put on a dual exhaust, it will cause backpressure. Sure dual exhaust looks nice, but its really for show cars and not GO cars unless it already had a dual exhaust like the new 350z.Sodikai said:thanks for the advice!
