Headers - Dodge 5.7L Hemi Truck

The Hedman Headers for Dodge 5.7L Hemi Truck deliver a direct bolt-on solution to unlock airflow potential in your Ram truck's exhaust system. Engineered specifically for 2003–2007 Dodge Ram full-size trucks, these street headers replace the factory cast manifolds with tuned primary tubes designed to improve scavenging and reduce exhaust backpressure. Whether you're building a weekend cruiser or seeking measurable gains from your stock or modified Hemi engine, these headers address one of the most effective first-step modifications a truck owner can install.

Constructed from mandrel-bent steel and finished in durable black paint, these headers feature 1.5-inch primary tubes that balance mid-range responsiveness with high-rpm flow characteristics typical of street applications. The stock collector flange ensures direct fitment to your existing exhaust system without requiring adapter fabrication or secondary modifications. Hedman engineers the tube diameter and bend radius to optimize exhaust velocity while maintaining practical street-driving characteristics—avoiding the excessive scavenging effects that can hurt low-end torque on full-size trucks. Gaskets and hardware are included, streamlining installation and reducing the need for separate fastener sourcing.

Ram truck owners running the Mopar Gen III Hemi benefit most from this pairing, especially those planning further bolt-on work such as intake upgrades or tuning. The 1.5-inch tube size works well with stock and mildly modified camshaft combinations, delivering noticeable throttle response improvements without requiring complete exhaust system redesign. Installation requires basic mechanical skills and hand tools; the stock collector design means no welding or custom exhaust work is necessary. These headers are sold as a pair, covering both driver and passenger sides of your truck's engine bay.
