Experience the incredible sound, fit, and style of the Invidia N1 Racing Cat Back Exhaust for your GD WRX/STi. Simple installation - remove old exhaust, install Invidia N1, and start your engine. In addition to a powerful exhaust note, this system's minimal bends and larger piping diameter allow for maximum flow and a significant boost in horsepower and torque.

Note: If you're using the factory downpipe, you will need to add a catback adapter as well!
