Agency Power Racing Downpipe Subaru WRX/STI 02+

Continually developing and enhancing the Subaru WRX and STI cars has been the goal of Agency Power. With a complete line up to make your Subaru the best in it's competition, Agency Power has just released their all new Racing Downpipe. This downpipe fits all Subaru WRX or STI cars from 2002 and up. The downpipe is full stainless steel with a cast bell mouth upper section. The thich flanges ensure a tight and strong seal. The downpipe deletes both your catalytic converters and bolts to all factory style turbos. The downpipes precision welds and polished piping give the AP Racing Downpipe that cutting edge. Each downpipe includes a bung for an aftermarket air/fuel sensor as well as a bung for the factory O2 sensor.

When adding an Agency Power Racing Downpipe to your Subaru WRX or STI, you will gain more horsepower and overall performance. The downpipe allows for better flow of the turbine and wastegate gasses. Unlike the factor downpipe that blocks the wastegate gasses from being released in an efficient manner, the AP downpipe has a large bell mouth which allows for both to flow smoothly out and down the pipe. The 3 inch diameter piping is the perfect size for the turbo cars from stock hp to 500 whp. The bellmouth will also allow for a little boost increase since there is less restriction. Mate this downpipe up with your aftermarket catback exhaust or one of our Agency Power catbacks for an amazing sound and almost 25 wheel horsepower gain.
