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

Gibson is well-known for exhaust components that help your truck breathe easier, and these performance headers are a prime example. Designed for a range of GM trucks like the 1999-2001 Chevrolet Silverado 1500, 2000-2001 Chevrolet Tahoe, and 1999-2001 GMC Sierra 1500, these headers replace your factory exhaust manifolds to unlock more usable horsepower and torque, especially at lower and mid-range RPMs where you need it for highway cruising. They are built with 16-gauge steel and feature 1-5/8 inch primary tubes, which are sized to improve your engine's ability to expel exhaust gases, leading to cooler operating temperatures and a more efficient engine.

These headers are designed as a direct replacement, using OEM-style connections so you don't need to cut or weld anything to install them. The 3/8 inch heavy-duty laser-cut port flanges are built to resist warping and leaking, ensuring a solid seal. They come with premium gaskets and hardware, making the installation straightforward. Plus, they are 50-state street legal, meeting EPA and CARB requirements, so you can install them with confidence. The ceramic coating not only looks good but also helps to further manage heat.

This header set is well-suited for both lowered and raised vehicles, whether you use your truck for street driving or off-road adventures. They are designed to work with the stock crossover pipe and use factory-style connections, meaning they should integrate smoothly into your existing exhaust system. Gibson backs these headers with a lifetime limited warranty, giving you peace of mind with your investment.
