Every Invidia downpipe features 3" diameter stainless steel piping, thick flanges, and a cast upper section for optimal flow and performance.

*Bellmouth: This design has a wide-open bell at the turbo, which is better for larger turbochargers with more flow. It will work fine with a stock or small turbo, but it is designed for scenarios where wastegate turbulence is not an issue.

*Note this downpipe does not feature a cat. Invidia's catless downpipe will cause a (CEL). You can use a software solution such as the COBB AccessPORT to eliminate these codes.

Fits all 2002-07 Subaru WRX, 2004-07 STI and 04-08 FXT.
