Cobb 15-20 Subaru WRX CVT / 14-18 FXT GESi Catted 3in. SS Resonated J-Pipe
The COBB Tuning GESi Catted 3" J-Pipe begins with a CAD-designed 4" cast bellmouth that smoothly blends air exiting the turbocharger's turbine housing straight into the GESi High Flow Catalytic Converter. Minimizing turbulence when exhaust gasses from the wastegate join into those flowing through the turbine helps to prevent excessive back-pressure.
A welded bracket utilizes the factory hard mount near the transmission reducing stress on the turbocharger mounting bolts and studs.
Corrosion-resistant and mandrel bent 3" 304 Stainless Steel tubing carries exhaust gasses downstream into a COBB-exclusive GESi 300 cell high flow catalytic converter. A second O2 bung is located directly after the catalytic converter and is to be used by the OEM Rear O2 sensor.
A CAD-designed, cast 304 stainless steel, flange finishes off the tail section of the J-Pipe. The reinforced cast flange is less susceptible to warp during assembly and for those of you installing with the strength of Hulk. A stainless adapter flange and included MLS gasket allow direct fit with the factory exhaust or COBB Cat-Back Exhaust utilizing the OEM donut gasket. Included COBB proprietary shoulder nuts allow installation of the factory spring bolts without fuss.
*NOTE: COBB Charge Pipe Kit is required for installation.
