Product Details
Starting with 3/8 inch thick, laser-cut port flanges, these Gibson headers are built to prevent warping and leaks, ensuring a solid seal right from the start. They're designed as a direct replacement for your factory exhaust manifolds on 2003-2008 Dodge Ram 1500 trucks with the 5.7L engine, using the stock crossover pipe and OEM-style connections. This means no welding is required for installation, making it a more straightforward job.
The headers use 16-gauge, 409L stainless steel tubing that's mandrel-bent for smooth exhaust flow. This improved flow helps your engine breathe easier, which can lead to more usable horsepower and torque, especially at lower and mid-range RPMs where you use it most for highway cruising and towing. The ceramic coating is rated to handle temperatures up to 1300 degrees Fahrenheit, helping to keep underhood temperatures cooler and protecting the tubing itself. Gibson includes premium gaskets and hardware to complete the installation, and these headers are 50-state street legal, meeting EPA and CARB requirements.
These headers are a well-suited upgrade whether your Ram is lowered or lifted, intended for street use or off-road adventures. They come backed by a lifetime limited warranty from Gibson, giving you peace of mind with your investment.
