Kooks 03-13 GM 1500 Series Truck/SUV 4.8/5.3/6.0/6.2L 1-5/8in x 1-3/4in SS Headers w/o EGR

Crafted from T304 aircraft-quality stainless steel, these Kooks Torque Series headers are built to last and perform. They feature a stepped primary tube design, measuring 1-5/8 inches and stepping up to 1-3/4 inches, which helps optimize exhaust flow across a range of engine speeds for your GM truck or SUV. This design is specifically tuned to work with the factory bolt pattern and connects directly to your OEM catalytic converters, meaning no additional parts are needed for installation. This makes them a solid option for owners of popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, and Cadillac Escalade, covering a wide range of years from 2003 to 2014.

Kooks has been a leader in high-performance exhaust for over 50 years, and these headers are a testament to that experience. Each set is handcrafted in the USA and undergoes dyno and race testing to ensure they make the most power possible for your application. The flanged collector outlet is designed for a direct fit with your factory catalytic converters, simplifying the installation process. This attention to detail in both materials and design means you're getting a well-built component that's made to fit and install the best.

Included with your headers are the necessary gaskets and bolt kit, so you have what you need to get them installed. Kooks backs these headers with a limited lifetime warranty to the original purchaser, reflecting their confidence in the product's durability and performance. Please note that these headers are not CARB approved and cannot be shipped to California.
