    Performance Gains. If you want to increase your 5.3L Sierra's horsepower and torque, look no further than the Kooks 3-inch Green Catted Y-Pipe. Adding this Kooks Y-Pipe with the required Kooks Long Tube Headers to your truck will boost overall performance, thanks to the Y-Pipe's 49-state EPA certified green catalytic converters.

    Bold Sound. Once installed, the Kooks Green Catted Y-Pipe with 3-inch inlet provides an aggressive note to the stock exhaust. This clear sound results from the pipe's "Y" crossover style. There's nothing like speeding down the road with a nice loud sound in your wake.

    Top Quality Materials. This product is constructed of mandrel bent 16-gauge stainless steel tubing, with a "Y" design for high stability and better exhaust flow. The pipe weighs 29 lbs. and has an OEM outlet that connects the matching Kooks Long Tube Headers to the stock cat-back exhaust. Follow the included installation guide for proper fitment.

    Application. The Kooks 3-inch Green Catted Y-Pipe is made for 2014 to 2018 5.3L V8 GMC Sierras, and it must be used with the corresponding Kooks Long Tube Headers (sold separately). It is not California street-legal.
