What Size of Exhaust Pipe Do I Need?

Simply put yes, the size of your exhaust pipe and mufflers makes a difference in the performance of your vehicle. Too small of an exhaust pipe size and you will restrict your engine of the horsepower it is capable of. Too large of an exhaust pipe size can also hinder performance, especially low RPM torque.
