The Q300 exhaust is an more refined performance exhaust system for the Subaru WRX. Using a high flowing muffler design and 3" piping, it amplifies the boxer sound of the engine but only to a degree. Sound is held in check but still sounds great when you're on the throttle. Power is increased by relieving back pressure and letting the turbo breather easier through a larger diameter pipe. Fitment is straight forward and installation is very simple with the Invidia exhaust on the Subaru WRX.
