Agency Power Catless Downpipe 2008-09 Subaru WRX STI

Agency Power has always had the goal of improving and enhancing the 2008-09 Subaru WRX and STI cars. Agency Power has just released their all new Racing Downpipe that fits all Subaru WRX or STI cars from 2008 and up. The downpipe is full stainless steel with a bell mouth upper section. The 0.4" thick flanges ensure a tight and strong seal. The downpipe deletes both your catalytic converters and bolts to all factory style turbos. The precision welds and mirror polishing piping give the Agency Power Racing Downpipe a show finish. 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 2008-09 Subaru WRX or STI, you will gain more horsepower and overall performance. The downpipe allows for better flow of the turbine and wastegate gass. Unlike the factory downpipe that blocks the wastegate gass from being released efficiently. The 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.
