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+ 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!
Designed to last a lifetime, the MAPerformance 2015+ Subaru WRX downpipes are available in either a catted or catless version for those customers without any restrictions on emissions.
