** ECU programming is required with the installation of this product **



The Lachute Performance catted 2.5" J-Pipe begins with an enlarged bellmouth that increases air exiting the turbocharger's turbine housing straight into the High Flow Catalytic Converter therefor minimizing turbulence when exhaust gasses from the wastegate join into those flowing through the turbine helps to prevent excessive back-pressure and increased flow.


A welded bracket utilizing the factory hard mount near the transmission reducing stress on the turbocharger mounting bolts and studs.


Corrosion resistant and mandrel bent  in 2.5"- 3" sizes made of 304 Stainless Steel tubing carries exhaust gasses down stream into a  high flow catalytic converter or a "Race or Offroad" version without.  


A 304 stainless steel, flange finishes off the tail section of the J-Pipe. A stainless adapter flange allows direct fit with the factory exhaust or Lachute performance Cat-Back Exhaust.


A Catted 3" J-Pipe is one of the premier modifications Subaru owners look to upgrade on their vehicle. By opening the diameter of exhaust flow coming out of the turbo, the downpipe unleashes power where the stock restrictive unit lacks.
