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 competition, Agency Power has just released their all new Racing down pipe. This down pipe fits all Subaru WRX or STI cars from 2002 to 2007. The down pipe is full stainless steel with a cast bell mouth upper section. The thick flanges ensure a tight and strong seal. The down pipe deletes both your catalytic converters and bolts to all factory style turbos.
The Down pipes precision welds and polished piping give the AP Racing down pipe that cutting edge. Each down pipe 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 down pipe to your Subaru WRX or STI, you will gain more horsepower and overall performance.
The down pipe allows for better flow of the turbine and waste gate gasses. Unlike the factor down pipe that blocks the waste gate gasses from being released in an efficient manner, the AP down pipe 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 bell mouth will also allow for a little boost increase since there is less restriction. Mate this down pipe up with your aftermarket catback exhaust or one of our Agency Power catbacks for an amazing sound and almost 25 wheel horsepower gain.
