Better Performance. Get more power behind your Sierra's back wheels when you install the Kooks Green 3-inch Catted Y-Pipe that features 49-state EPA certified green catalytic converters. The upgrade, which requires the corresponding Kooks Long Tube Headers, will provide better exhaust flow for more horsepower and torque.

The Sound You Crave. This Kooks Green Catted Y-Pipe delivers clear, aggressive sound once connected to the stock exhaust, thanks to the "Y" crossover design of the pipe. In addition to the great sound, you'll love the sharp look of the stainless steel tubing and mandrel-bent, 16-gauge construction. Your vehicle will experience gains in horsepower and torque, making you the most envied driver on the road.

Installation. Installing the 25-pound Catted Y-Pipe with 3-inch inlet requires connecting the matching Kooks Long Tube Headers to your truck's OEM catback exhaust. Kooks designed this product with an OEM outlet for an easy installation and a great fit. Refer to the included installation guide while performing the upgrade.
