Here, you are looking at the HKS Carbon-Ti Cat-Back Exhaust System. This is a great way to improve the performance and the sound of your vehicle. HKS designed this muffler using premium stainless steel materials along with smooth mandrel bends and larger piping diameter. The result is improved throttle response all while providing an aggressive exhaust note.
Fitment note: This exhaust was designed for the bumper cutout of the 2004-2007 WRX and WRX STi. It CAN be installed on the 2002-2003 WRX, but the tip will contact the bumper. You could modify the bumper, or use some Kartboy extended exhaust hangers to lower the muffler.
Fits all 2004-2007 Subaru WRX and WRX STI; also 2002-2003 with the caveats mentioned above.
