2015-2020 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 2015-2020 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!


  • 3.5" bell mouth to 3" design reduces exhaust restrictions
  • Made from 304 stainless steel for superior corrosion resistance and enhanced appearance
  • Mandrel-bent tubing throughout optimizes exhaust flow
  • Stainless steel flex section reduces stress from engine movement increasing longevity
  • Utilizes OEM ground strap
  • Designed to be used with your OEM turbo outlet gasket
  • 304 stainless steel CNC turbo outlet flange
  • 100% Made in the USA

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

May also work with other catbacks, please contact us with any questions!
