This is Circuit Werks new Front Over Exhaust Pipe that connects the header to the mid-pipe for the Scion FRZ / Subaru BRZ / FT86. This front pipe is made from stainless steel for increased strength and straight piped (non resonated). This front pipe comes with the hardware and gaskets as well.
This front pipe eliminates the stock smaller piping and reduce exhaust back pressure by maximizing exhaust flow which gives a increase in horsepower. The result brings out the vehicle's performance potential by giving it a high free flow exhaust system.
