XForce 100CPSI high flow catalytic converter downpipe for Subaru Impreza WRX SEDAN 2L FA20 2015-2017, stainless steel.

The XFORCE 3-inch downpipe for Subaru WRX sedan owners removes a substantial factory restriction. The large-bore 304-grade stainless steel piping and motorsport 100-cell high-flow cat, when combined, significantly reduce back pressure, unleashing more power and more torque throughout the rev range. Due to the added exhaust gas flow, a re-tune is recommended to complement the added performance and to turn off the engine warning light (EML). Bolts to factory turbo. 3-inch piping. 100-cell high-flow catalytic converter. 304-grade stainless steel for exhausts. Manual vehicles only. Note: This product is equipped with a 100 cSpi sports catalytic converter, exclusively designed for track use, and may not pass emission tests. Please verify if high-efficiency catalytic converters can be used on roads in your country. Xforce offers a range of uniquely designed and engineered stainless steel bolt-on exhaust systems. These exhaust systems bolt directly to existing mounting points, making installation a breeze. They are built for good performance, with materials designed for a long lifespan, and like all Xforce exhaust systems, they look great!
