Product Description

The Gibson GP312S Performance Header is a direct-fit stainless steel shorty header designed exclusively for the **2004-2005 Dodge Ram 1500 SRT-10 equipped with the 8.3 L V10 engine**. Engineered with mandrel-bent 1.50" diameter 16-gauge tubing and heavy-duty laser-cut port flanges, this header improves exhaust flow and helps your engine breathe more efficiently compared with the restrictive factory exhaust manifolds. The result is cooler engine operation along with improved low- and mid-range horsepower and torque - ideal for both street performance and towing applications.

Installation is straightforward with a direct bolt-on design that uses OEM-style connections and attaches to the stock crossover pipe, eliminating the need for welding or custom modifications. Premium gaskets and all required hardware are included to simplify installation. This header is 50-state emissions legal - compliant with both EPA and CARB regulations - and designed not to affect your vehicle's factory warranty.

The GP312S is dyno-tuned to increase airflow and reduce backpressure, helping the 8.3 L V10 deliver stronger throttle response and torque at everyday driving speeds. Its stainless construction and heavy-duty flanges ensure durability and resistance to corrosion for long-term use on both street and off-road rigs. This makes the Gibson GP312S a strong performance upgrade for 2004-2005 Dodge Ram 1500 SRT-10 owners looking for improved engine efficiency and responsiveness.
