MAP WRX Catted Downpipe Rev 4 | 2015-2020 Subaru WRX MT (WRX-4G-DPC-REV4)

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!
