      Improved Off-Road Performance. Upgrade your Jeep's exhaust with the  Kooks 3 in. Catted Y-Pipe. Designed for use with Kooks headers and cat-backs, this catted Y-pipe improves exhaust flow for increased horsepower and torque output. Additionally, it can be used with custom cat-backs.

      High-Performance Growl. The large, 3.0-inch tubes give the Jeep's exhaust increased tone and volume. Note that Y-pipes do add some rasp to the sound.

      Includes Kooks High-Flow  Catalytic Converters. The catted Y-pipe replaces the factory cats with high-performance catalytic converters, allowing it to be driven on roads and streets. However, note that the Y-pipe is not CARB certified or exempt at this time and is not legal for use in California or states adopting California emission standards.

      Superior Construction. The  Kooks 3 in. Catted Y-Pipe is specially designed with the latest CAD technology and uses CNC precision-machining. The high-grade stainless steel is strong and durable for long-lasting service.

      Application. The Kooks 3 in. Catted Y-Pipe is designed to fit 2007 to 2018 Jeep Wrangler JK models with LS Engine Swap.
