2015-2021 Subaru WRX MT Rev 4 Catted Downpipe by MAPerformance

When the turbo compresses exhaust gas, it's forced through a narrow downpipe on its way through the exhaust system. This narrow pipe can create lots of turbulence. This air pressure needs to go somewhere, and the factory 2015-2021 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!

Please Note: This will not fit CVT models. This product may be used with either a factory cat-back exhaust system or an aftermarket exhaust system. Please specify via the dropdown before ordering.
