Review 1ST-RACING Exhaust Manifold Hardware Dodge 5.7 V8 fits RAM HEMI 1500 2500 3500 2003–2008

The 1st Racing HD-DG570308ZXLUS Exhaust Manifold is a high-performance upgrade for the 2003-2008 Dodge Ram 1500, 2500, and 3500 pickups equipped with the 5.7L Hemi V8 engine. This exhaust manifold is designed to provide superior flow and durability compared to the factory manifold, resulting in increased horsepower and torque.

The manifold is constructed from heavy-duty, investment-cast 4130 stainless steel. This material offers superior strength and corrosion resistance, ensuring that the manifold can withstand the rigors of heavy-duty use. The castings are also CNC-machined to ensure precision and consistency in each piece.

Another feature of this exhaust manifold is its integrated exhaust gas recirculation (EGR) system eliminator. This eliminator removes the restrictions and complexities of the factory EGR system, allowing for a more straightforward and efficient exhaust flow. This can lead to further power gains and improved engine performance.

The 1st Racing HD-DG570308ZXLUS Exhaust Manifold also includes redesigned exhaust header bolts, which are made from high-strength material and feature a larger diameter than the factory bolts. This ensures a secure and reliable installation, as well as easier removal and installation in the future.

Overall, the 1st Racing HD-DG570308ZXLUS Exhaust Manifold is a top-quality upgrade for the Dodge Ram Hemi V8 engines. It offers improved flow, durability, and power output, making it an ideal choice for anyone looking to get the most out of their truck's engine.
