GrimmSpeed Stainless Steel Catted J-Pipe For 2015 - 17 Subaru WRX 6 Speed Manual
The GrimmSpeed Catted J-Pipe for the 2015-17 Subaru WRX 6 Speed Manual Transmission is constructed from (1) mandrel bent 3" 304 stainless steel pipe. The pipe has a smooth 3.5" to 3" transition that matches the OEM turbocharger outlet size and then reduces quickly to maintain exhaust velocity. The J-Pipe features 1/2" high quality stainless steel flanges that are TIG welded and CNC machined to fit and clear the OEM components. The GS Catted J-Pipe integrates a 300 cell metallic substrate catalytic converter that balances reduced restriction and the foul smell of a 200 cell cat. The J-Pipe includes custom stainless steel replacement turbo studs, 3rd O2 sensor bung for use with aftermarket sensors and grounding strap mount.
*Expect approximately 45whp / 70wtq when combined with a custom ECU recalibration.
