Fits 2004-2005 Dodge Ram 1500 SRT-10 (8.3L).

Engineered for specific performance gains on the Viper-powered Ram, this Gibson Performance Header (MPN: GP312S) is dyno-tuned to increase usable horsepower and torque in the low and mid-range RPM bands. Designed as a direct bolt-on replacement for restrictive factory manifolds, these headers utilize the stock crossover pipe and OEM-style connections for a clean installation with no welding required.

The construction features mandrel-bent 409L stainless steel 16-gauge tubing to ensure consistent exhaust flow and heat management. Heavy-duty 3/8-inch laser-cut port flanges provide a precise seal to the cylinder head, preventing warping or exhaust leaks under high operating temperatures. This system is 50-state street legal, meeting EPA and CARB requirements without affecting your factory warranty.
