3" J-Pipe / Intermediate-Pipe (2015+ WRX and 2014+ Forester)
Fits Manual and CVT Transmissions!

Each piece uses 3D CNC ported 1018 cold rolled steel flanges mated to 304 stainless 3" tubing. All products are handmade and checked for perfect fitment.

This J-pipe / Intermediate pipe assembly will be 2 pieces, giving customers the ability utilize the factory catalytic converter by using only the downpipe. A catted J-pipe will not be offered because there is no way for us to include a high quality cat for an affordable price. Most aftermarket cats offered with other J-pipe assemblies are inferior compared to the OEM cat. Using the upper J-pipe will make the exhaust system catless.

A premium stainless flex section is used to allow movement in the exhaust to reduce the risk of cracking

Optional additional o2 bung for customers using a wideband sensor.

Combo Gains:
Increased spool
Average 20-30 hp and tq gain throughout the midrange
12 whp / 33 ft/lbs tq at peak

Dyno numbers are based off of a bone stock 2015 WRX with ETS 3" cat-back exhaust and Cobb Stage 1 reflash on an AWD Dynojet on the same day with 3 back-to-back pulls with each mod to check for consistency.
