    Boosts Vehicle Performance. If you’re all about off-roading, then you want to eke out every ounce of performance from your vehicle. The Kooks 3 in. Off-Road Y-Pipe removes those pesky factory catalytic converters to drastically improve your exhaust gas airflow. This increases your Chevy Silverado’s horsepower and torque for an unparalleled off-roading experience.

    Helps Create a More Aggressive Exhaust Note. Because of its free-flowing design, the Kooks Off-Road Y-Pipe does more than improve your truck’s performance. It also adds a louder and more aggressive exhaust note.

    Removes Factory Catalytic Converters. This Kooks Y-Pipe eliminates your Chevy Silverado’s stock catalytic converters. This means that this Y-Pipe is not CARB Certified, and is not street-legal in California or any other state with similar emission standards.

    Application. The Kooks 3 in. Off-Road Y-Pipe is compatible with 2014-2018 5.3L Chevrolet Silverado 1500s equipped with Kooks Long Tube Headers.

    1 Top Rated Question

    does kooks or other brand offer y pipe to connect to stock manifolds? with or without cats ? my stock y pipe has 3 cats . would it help to eliminate 3rd cat ? has o2 sensors in front and behind front 2 cats . or eliminate all 3 cats? 2018 5.3 silverado

    • At this time we do not offer any Y pipes that connect to the stock manifolds. Horsepower gains removing the cats have been shown to be very minimal on stock and lightly modified Silverados, typically netting 2-5hp. Heavily modified and supercharged Silverados due tend to get a much better benefit from cat removal.
