There are plenty of way to open up additional power for your Scion FRS. One way to do this is by adding a high quality header to your car. No other company manufacturers 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 2013 and up Scion FRS. This header is made from 304 stainless steel and includes half inch thick flanges. The headers have a special designed collector to give perfect flow for increased horsepower. The header can work with the factory exhaust or with the Agency Power stainless steel mid pipe (sold separately). Installing the header will not only gain 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.
