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!

Features

  • 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!

As advertised

Very nice part. Engineered well and fabricated beautifully. Fits perfect. Have been running this J pipe with v400 Cobb tune for about 1000-1500 miles so far and no CEL and passes the smell test which my previous high flow Cat J-pipe failed both. Price point is spot on, when pricing out components to fabricate myself it’s a fraction more to just buy the finished piece.

Great Product

Like others have said, this is the way the WRX should have come from the factory. This is a great product and matches perfectly with the MAP intake. I had it installed by a local shop and had no issues. For those that have the SPT exhaust from Subaru, you will need to get the adapter.

Good Quality

Its a great jpipe and very solid. I would give it 4.5 stars. There are a few minor issues (02 sensor no longer reaches the connector, no torque specs for v-clamp, the install video def missed some things and makes it seem easier then it is). I would buy again though. Good luck getting the bolts off though.

Top notch

Even with the new Cobb restrictions this doesn’t throw engine lights; only thing is could have included the grimmspeed stud kit with it.!
