Product Description

Invidia Divorced Catless Downpipe with extra O2 Bungs
The Invidia divorced wastegate style downpipe for the 2002-2007 WRX and STI features a separator plate to separate exhaust flow between the turbine and the wastegate, designed to reduce exhaust turbulence that can occur in internal wastegate turbochargers. Invidia divorced style turbochargers for the 2002-2007 WRX & STI are available with a high flow cat or completely catless.

FITMENT:
Subaru STI 2004-2007
Subaru WRX 2002-2007

Invidia offers downpipes for the Subaru WRX & STI that are designed in three different configurations. Every Invidia WRX & STI downpipe features 3" diameter stainless steel piping, thick flanges, and a cast upper section for optimal flow, performance, and longevity.

Invidia's catless downpipes will cause a Check Engine Light (CEL) on your 2002-2007 WRX or STI. While this isn't harmful, it can be annoying and disables the cruise control, but you can use a software solution such as the Cobb Accessport to eliminate these codes and make more use of the newly available performance the Invidia downpipes offer. The high-flow cat Invidia WRX & STI downpipe is not emissions legal, and may still cause a CEL, but it does help to reduce boost spiking on 2.5L cars.
