      Better Performance. Take your Sierra to the next level of performance while off-roading by installing the Kooks 1 3/4-Inch Long Tube Headers under the hood. The four-tube design is crafted for more RPM horsepower and torque than the factory design. You'll be able to feel the difference as you cruise down the road.

      Aggressive Look. Once installed, the stainless steel tubing with its natural finish adds to the bold appearance of the engine. The style is evident as soon as you pop open the hood. The Kooks long headers complement the rugged design of your truck very well.

      Strong Design. The Kooks Long Tube Exhaust Headers are made of 18-gauge stainless steel tubing, measuring 1 3/4" x 3", to provide excellent airflow. Kooks made sure this product has not only superior performance, but also a great fit. These headers require a matching Kooks Y-Pipe to install properly. All necessary installation hardware and gaskets come in the headers kit.

      Application. The Kooks 1-3/4-inch Long Tube Headers fit only 2014 to 2020 Sierras with 5.3L and 6.2L V8 engines. A proper installation requires the appropriate Kooks Y-Pipe (sold separately). It is not California street-legal.

      I’d like to install these on my 2011 Chevy 1500 Silverado with the 5.3 engine. I noticed on your add they are specified to fit 2014-2018. Any recommendations if they won’t work for a different setup? Sincerely, Jon

      so i already got the borla atak exhaust system with the side exits... question is what all do i need along with this long tube headers to complete the setup? do i need any other parts to go along with this headers to complete the setup?

      will these work with the borla atak exhaust?

      • These are compatible with the Borla Atak Catback System.

      will these headers work along with the borla ataks exhaust system?

      Is there any special fabrication that needs to be done to install. I heard you had to put spacers on your engine mounts to make clearance.

      • No spacers or fabrication should be required.
