Lachute Performance Catback - 2011-2021 WRX & 2011 -2021 STI

Completely assembled by hand and built from 304 stainless steel to provide a quality finish and a precise fitment.   Equipped with a 1/2 inch thick inlet flange for reduced distortion and a flex pipe to allow for movement, it is a true 3 inch catback all the way through. The inlet flange will also virtually fit any available J-Pipe/downpipe. A flex section was added to minimize vibrations and stress.   We’ve built this catback with multiple v-band flanges for a gasketless seal, ease of installation and better adjustability.  It Includes an adapter to fit to any downpipe that uses the stock donut gasket.   Available non-resonated and resonated so you can choose between a softer or more aggressive sound.    Warning: This product may contain a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm.
