A must for engines with a restrictive exhaust manifold that can limit operating efficiency and result in sluggish performance
Ideal for street or strip-;at a fraction of the cost of a Super Competition race header!
More HP! Improved mileage! The feel and sound of a smooth-running performance engine!
The easy way to add horsepower to your engine for a big performance boost! These competition Holley® headers are designed for the value-conscious enthusiast with a stock to mildly modified engine. They help restore power by letting your engine "breathe" better, operate more efficiently and run cooler. You'll enjoy faster acceleration and get more miles on a gallon of gas. Custom designed of durable 16-gauge mild steel tubing with tuned lengths for maximum performance. Long-transition collectors ensure reduced back pressure for increased exhaust flow. 5/16" machined flanges with welded O-rings make a perfect sealing surface. Superior weld design lasts longer under extreme weather/temperature conditions. Easy to install on stock replacement and most aftermarket heads with an angle-plug configuration. Will not fit most aftermarket racing heads with raised exhaust ports. Headers, gaskets and hardware included. Not equipped with smog fittings. Sold in pairs. Shipped separately from factory.
