Gibson 02-03 Dodge Ram 1500 SLT 4.7L 1-1/2in 16 Gauge Performance Header - Stainless

Starting with 3/8 inch thick, laser-cut port flanges is key to a solid header installation. These Gibson headers for your 2002-2003 Dodge Ram 1500 with the 4.7L engine use these substantial flanges to prevent warping and ensure a leak-free seal against the cylinder head. This is a direct replacement for your factory exhaust manifolds, meaning no welding is required, and it uses the stock crossover pipe for a straightforward swap. The 1-1/2 inch primary tubing is constructed from 16-gauge 409L stainless steel, chosen for its resistance to corrosion and durability under heat.

These headers are designed to help your engine breathe more freely, which can lead to improved horsepower and torque, especially in the low and mid-range RPMs where you use it most for highway cruising and towing. Cooler engine operating temperatures are also a notable benefit. Gibson tunes these headers on a dynamometer to optimize their performance, ensuring they work well with both stock and slightly modified vehicles, whether they're lifted or lowered, used on the street or off-road. Plus, they meet EPA and CARB requirements, making them 50-state street legal and designed not to affect your factory warranty.

Included with the headers are premium gaskets and all the necessary hardware for installation, simplifying the process. The mandrel-bent tubing maintains a consistent diameter throughout, which is crucial for smooth exhaust flow. Gibson backs this header with a lifetime limited warranty, giving you confidence in its long-term performance.
