Product Details
Agency Power AP-GDA-175 Stainless Steel Header Subaru WRX/STI 02+

Your Subaru WRX or STI needs more power. One way to do this is by adding a high quality header to your car. No other company manufacturer high quality, power producing, and cost effective parts like Agency Power. The all new Agency Power stainless steel header kit is now available for your 2002 and up Subaru WRX and STI. This header fits either the 2.0L or 2.5L engines. This header is made from 321 stainless steel and includes inch thick flanges. The headers have a special designed collector to give perfect flow into the uppipe providing faster turbo spool and increased horsepower. The header can work with the factory uppipe or is sold with the Agency Power stainless steel uppipe. Installing the header will not only gain you about 15 wheel horsepower, it will also change the tone of your Boxxer engine to a deeper and more aggressive sound. It is recommended to change the gaskets when installing this header kit. For questions on fitment, installation, or the product, please contact a sales associate.
