Product Details

This Gibson Performance Header kit for your 2011 Chevrolet Silverado 2500 HD LT with the 6.0L engine includes the stainless steel headers, premium gaskets, and all necessary hardware for installation. These headers are designed as a direct replacement for your factory exhaust manifolds, meaning no welding is required and they use OEM-style connections, making installation straightforward. They are built with 3/8" heavy-duty laser-cut port flanges to prevent warping and leaks, ensuring a solid seal.

Gibson headers are dyno-tuned to help your engine breathe better, which can lead to more usable horsepower and torque, especially at the low and mid-range RPMs you use most often during highway driving. This improved airflow can also contribute to cooler engine operating temperatures. They are well-suited for various vehicle setups, whether your truck is lowered or raised, and are street or off-road ready. Importantly, these headers meet EPA and CARB requirements and are 50-state street legal, so you can install them with confidence. They are also designed not to affect your factory warranty.

The stainless steel construction means these headers are built to last and resist corrosion. Gibson backs this product with a Lifetime Limited Warranty, giving you peace of mind with your investment.
