For a strong boost in power, the Invidia Down Pipe offers an alternative to other power-boosting enhancements. They sport a one-piece design, eliminating the need for the stock catalytic converter. The quality on these downpipes is second to none and has to be seen to be believed. In addition, each Invidia Down Pipe can be bolted up to any Invidia Exhaust or a stock exhaust for an easy installation.
Notes

Beautiful downpipe. Easily added horsepower and great sound. Installation fit just like factory and nicely bolted up to the Invidia N-1 catback I already had. The reason I rate it a 9 is because on an STi, boost spike/creep is an issue with downpipes (not so much on the WRX). If you want to run a performance downpipe, PEASE get some kind of engine management (Cobb AP, TurboXS UTEC, etc.) Boost creep cracks pistons and destroys rods. Engine management helps to prevent 99% of boost creep. Other that that, the downpipe is awesome and I would highly reccommend it to anyone!
