Gibson 99-01 Chevrolet Silverado 1500 Base 4.8L 1-5/8in 16 Gauge Performance Header - Ceramic Coated

Gibson is well-known for making exhaust components that help your truck breathe easier and perform better. This performance header, part number GP115S-C, is designed to replace the factory manifolds on a range of vehicles, including the 1999-2001 Chevrolet Silverado 1500, 2000-2001 Chevrolet Tahoe, and 1999-2001 GMC Sierra 1500. By improving your engine's ability to expel exhaust gases, these headers can lead to more usable horsepower and torque, especially at lower and mid-range RPMs, making highway cruising and towing more responsive.

These headers are constructed from 16-gauge steel with 3/8-inch thick laser-cut port flanges. This robust construction helps prevent warping and leaks at the exhaust ports, ensuring a solid seal. The ceramic coating not only gives them a clean, finished look but also helps to keep under-hood temperatures cooler, which can benefit overall engine operation. They are designed to use OEM-style connections and the stock crossover pipe, meaning no welding is required for installation, and they utilize factory connection points for a straightforward swap. Premium gaskets and hardware are included to help ensure a leak-free installation.

This header is street legal in all 50 states and meets EPA and CARB requirements, so you can install it with confidence. It's well-suited for both lowered and raised vehicles, whether you use your truck for daily driving on the street or for off-road adventures. Gibson backs this header with a Lifetime Limited Warranty, reflecting their confidence in the product's durability and performance.
