Description
Improves Driving Performance. Equipping your truck with these Kooks 1-7/8-Inch Long Tube Headers with GREEN Catted Y-Pipe will help improve its driving performance. With their optimized 1-7/8-inch tubing diameter, your vehicle’s toxic fumes can flow freely, resulting in an improved exhaust flow, as well as combustion process. This then gives your truck an increase in horsepower and torque, allowing it to exhibit a faster and more powerful driving performance.
Louder Exhaust Note. Compared to stock, these long tube headers generate a much louder exhaust sound. So, if you want to enhance your vehicle’s exhaust tone, then install these long tube headers instead of fully replacing your exhaust system.
Green Catted Y-Pipe. These long tube headers are built with a green catted Y-pipe. This helps the headers to release cleaner emissions, making them better to use for environment-conscious drivers.
Stainless Steel Construction. To withstand the corrosive effects of various road and weather elements, these long tube headers are made of 304 stainless steel. This material also makes your new headers highly resistant to hot temperatures and impacts, preventing them from easily deforming. Furthermore, these headers sport a natural stainless steel finish, allowing them to match most styles of vehicles.
Application. These Kooks 1-7/8-Inch Long Tube Headers with GREEN Catted Y-Pipe are created to fit 2019-2025 5.3L Sierra 1500 models.
Kooks GREEN Catted products are rated for forced induction applications making up to 750 RHWP and are built to EPA specifications.
