Invidia offers both catted and catless divorced style downpipes for the 2008-2010 WRX 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 WRX 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.
