Invidia's Q300 catback exhaust system for the 2011-2014 WRX or STI sedan provides a great alternative to the standard N1 style exhaust system without compromising power or quality. Traditionally, if you wanted a quieter exhaust system, you had to sacrifice performance to get there. Not any more. Enter the Q300 series performance exhaust from Invidia. Q300 exhaust systems utilize specially sized resonators and muffler baffles to maintain power output while still producing a deep and mellow touring exhaust tone. Still skeptical? The Invidia Q300 will increase horsepower and torque tremendously all without disturbing the neighbors or raising the eyebrows of any local authorities. The ultimate in stealth power! Invidia exhaust systems include all hardware and gaskets needed for a seamless installation on your WRX or STI sedan.
Available with your choice of quad stainless steel or burnt-titanium exhaust tips.
Fits all 2011-2014 Subaru WRX and WRX STI sedan. Does not fit hatchback models.
