Gibson 05-06 Chevrolet Avalanche 2500 LS 8.1L 1-3/4in 16 Gauge Performance Header - Ceramic Coated

This Gibson performance header kit includes the header tubes, premium gaskets, and all necessary hardware to get your truck breathing better. It's designed as a direct replacement for your factory exhaust manifolds, using OEM-style connections so you won't need to do any welding. This header is built for a range of heavy-duty trucks and SUVs, including models like the 2004-2006 Chevrolet Avalanche 2500, 2004-2005 Silverado 2500 HD, and 2004-2005 GMC Yukon XL 2500.

Gibson tunes these headers on the dyno to help your engine make more usable horsepower and torque, especially at those crucial low and mid-range RPMs you use most often for highway cruising and towing. The 1-3/4 inch primary tubes are made from 16-gauge, 409L stainless steel, which is a well-built material that holds up well. They're coated with a high-temperature ceramic finish that can handle up to 1300 degrees Fahrenheit, helping to keep underhood temperatures down and resist corrosion. The port flanges are a solid 3/8 inch thick and laser-cut to ensure a flat, leak-free seal against your cylinder heads, preventing common issues like warping or leaks.

These headers are street legal in all 50 states, meeting both EPA and CARB requirements, and they won't void your factory warranty. They're a solid option whether your vehicle is stock height, lowered, or lifted, and they're suitable for both street and off-road use. You'll get a more efficient exhaust flow, which can lead to a cooler running engine and improved performance.
