• 2008–2021 Subaru | WRX

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.
