WRX Catted Downpipe Rev 2 | 2015-2020 Subaru WRX MT

2015-2020 Subaru WRX MT Rev 2 Catted Downpipe by MAPerformance When the turbo compresses exhaust gas, its forced through a narrow downpipe on it's way through the exhaust system. This narrow pipe can create lots of turbulence. This air pressure needs to go somewhere, and the factory 2015-2020 Subaru WRX downpipe is a huge bottleneck, limiting flow and robbing power. An upgraded downpipe will allow this spent exhaust gas a quicker outlet to the exhaust system, increasing horsepower and torque through the entire power band!
