i have a 2001 1.4 (6th gen) civic what would be the best exhaust system to get? also does anyone have any reviews on powerflow exhausts i was thinking about getting a custom made instead of a magnex etc exhausts.
over-sized exhausts do very little when it comes to horsepower gain unless the intake and throttle body have also been replaced. Then they can add from 10 to 20 peak hp. That said, My friend drives an rsx with a Greddy exhaust and loves it. It also looks very cool.
