This is Circuit Werks new Dual Resonated front exhaust test pipe for the Scion FRS / Subaru BRZ / FT86. This front pipe is made from stainless steel for increased strength and it has a dual resonated design to help illuminate drone compared to regular straight piped (non resonated) front test pipes. The most restrictive part on any exhaust system is the catalytic converter. This front pipe is easy to install and the hardware is included with the pipe as well. This will only fit on the manual transmission models.
The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of the exhaust gases to reduce the amount of harmful gases into the atmosphere. That is a potential performance restrain. This front pipe eliminates the stock catalytic converter 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.
