Invidia High Flow Cat w/ Extra 02 Bung Downpipe Subaru WRX 2008-2014 / STI 2008-2017


Invidia 08+ Subaru WRX/ 05-09 STI / 02 Legacy High Flow Cat Extra 02 Bung


Invidia offers both catted and catless divorced style downpipes that are designed with a separator plate between the turbine and wastegate exhaust streams. Divorced style downpipes reduce exhaust turbulence for exceptional exhaust flow and performance. Every Invidia downpipe features 3″ diameter stainless steel piping, 1/2″ thick flanges, and a cast upper mouth section. Please note that without engine management such as the Cobb Accessport, a catless downpipe will trigger a check engine light. Invidia now offers a 2 bung version to make tuning easier! A plug is included so you don’t have to run two sensors immediately.

Specs: 3″ exhaust gasket included, turbo to downpipe gasket sold separately.
