      • Don't give up looking for headers for your vehicle. Patriot offers headers for many applications at prices you can afford. Built with surface machined thick steel flanges for a great seal and mandrel bent mild steel tubing. Patriot headers are available raw or with metallic ceramic coating. Unlike paint or chrome, metallic ceramic coating is easy to keep clean, resist rust and corrosion and will not discolor. Metallic ceramic coating also reduces underhood temperatures. All Patriot headers come with installation hardware, collector reducers, gaskets and instructions.

      See More Details for Applications Listing.
