SuperMAXX® Stainless Long Tube Headers are an excellent way to bolt on 15 HP and 38.5 Ft. Lbs. of Tq. to your 2007 - 2013 GMC / Chevy 1500 Series Truck, H2 Hummer or SUV with a 4.8, 5.3, 6.0 or 6.2L engine. Although a tune is recommended, these power gains were before the tune! A power tune could add another 20-25 HP. 100% Stainless Steel construction with a Limited Lifetime Warranty makes the SuperMAXX® header second to none. 1.750 primary tubes and a 2.50 collector make a great combination for stock engines and/or upgraded power plants. Fits with automatic or manual transmissions and takes about 4-6 hours to install. Comes complete with a detailed, full color instruction manual for easy installation. Triple layer stainless steel gaskets, header bolts and all installation hardware are included. Designed for use with Dynatech® intermediate sections (part numbers 715-14120, 715-14130, 715-14220, 715-14230, 715-14320, 715-14330, 715-14420, 715-14430 or 715-14620).
