Invidia Subaru WRX/STI & 05-09 Legacy Twin O2 Sensor Bung Downpipe 08-UP
Invidia's downpipe is a great way to start adding Horse Power and Torque gains. The Invidia downpipe is constructed of 304 stainless steel tubing to ensure longevity while enhancing power by freeing exhaust flow. Mandrel bent piping will bolt up to any stock replacement catback or stock unit.
Your car must be tuned to take advantage of the potential gains with this downpipe
Because this product replaces/removes an OEM emissions control device we must state that this catless downpipe is for off-road use only.
