PRERacing Bell Mouth Downpipe - Fits 2002-2007 WRX & STI

This item has been discontinued. We recommend looking at the Cobb Catted Downpipe as an alternative.

With current EPA restrictions, catless downpipes are no longer an option for On-road vehicles. Our PRE Racing team has engineered a viable solution for maximum performance while maintaining current emission standards.

We've taken an Invidia Downpipe and fused it with the best converter available. This new G-Sport Gen2® High-flow catalytic converter yields the same performance gains as a catless downpipe, and the best part, it is EPA-approved! Now you can rest assured, knowing that your car will pass future emission tests while maintaining maximum performance.
