Full length chassis and fenderwell headers provide the ultimate in performance for Ford Mustang and Mercury Cougar cars with standard or high performance engines.

Full length chassis and fenderwell headers provide the ultimate in performance for Ford Mustang and Mercury Cougar cars with standard or high performance engines. Long primary tubes; result in more horsepower and torque than those from competitors. Additional features include a close fit to the engine block for maximum chassis and steering clearance; mandrel bent tubing that's available in your choice of bare or metallic ceramic coated finishes.

New gaskets and bolts are included.

Unless otherwise stated, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, engine mounts, body mounts and bushings, etc. If your vehicle is using aftermarket parts or parts from other applications, or customised/altered parts, then it is the installer's responsibility to verify fitment to your vehicle.
