SuperMAXX Stainless Non-Catted Intermediate Section is an excellent way to complete your Dynatech Header System on your 2007 – 2008 GMC / Chevy 1500 Series Truck or SUV with a 4.8, 5.3 or 6.0L engine. This system is all about increased power with a full race, straight through system from the header to the cat-back. 100% Stainless Steel construction with a Limited Lifetime Warranty makes the SuperMAXX header second to none. With a unique 2.50” “Ball & Socket” connection to the header and 2.50” tubes to connect to the factory or aftermarket cat-back, this makes 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. O2 Extension cables and all installation hardware are included. Designed for use with Dynatech Long Tube Headers (part number 715-14110).
