Patriot Exhaust H8403-1 Details

Coated Patriot Header for SBF Mustang (64-73), Falcon (66-70), Fairlane (66-73), Comet (66-69), Ranchero (66-73). Will not fit 351 Windsor

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, resists 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. Please see our online catalog for specific information like tube size, port shape and collector size.

Full length headers are typically used for higher RPM horsepower, but can also increase the mid range torque in applications were there is room to fit a long tube design.
Durable 18-gauge tubing
Comes complete with gaskets, header bolts and collector reducers.
Available in three finishes; raw steel for individual customizing, Hi-Temp Black Coating or Metallic Ceramic Thermal Barrier Coating
Limited One Year Warranty
