Invidia Catless Down Pipe ‘Aus Spec’ WRX/STI

The Invidia Catless Down Pipe features a Open Mouth Bell Mouth. Invidia’s all new Australian-spec Down Pipes are a great way to start getting performance HP and Torque.

The Invidia Down Pipe is constructed of 304 stainless steel tubing to ensure longevity while enhancing power by freeing exhaust flow. 3″ mandrel bent piping will bolt up to any stock replacement Cat Back or stock unit. And the Australian Designed Stainless Cast Head ensures perfect flow… This is the most advanced unit on the planet for flow and fitment. Invidia down pipes are covered by lifetime warranty.

Note- Steering Knuckles are not required with the Australian-spec Down Pipe. Also, due to all Subaru WRX/STI from 01-07 having different Down Pipes, you may need to lengthen the Cat Back to fit.
