Invidia offers downpipes for the 2002-2007 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 02-07 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.
Invidia now offers 2 bung versions of downpipes to make tuning easier! A plug is included so you don't have to run two sensors immediately.
Invidia Bellmouth Downpipe
The Invidia Bellmouth Downpipe for the 02-07 WRX & STI is designed to maximize exhaust flow to the highest level possible. Featuring a wide-open bell at the turbo, this downpipe provides the maximum exhaust flow possible on either your stock or aftermarket turbocharger setup. This product is a simple yet effective design that will net massive power and torque gains on your Subie.
Invidia Divorced Downpipe
The Invidia divorced wastegate style downpipe for the 02-07 WRX & 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 02-07 WRX & STI are available with a high flow cat or completely catless.
