Now available is American Racing Headers’ 100-percent American-made long tube 304 S/S header systems, which are designed to fit great, install easily and produce outstanding horsepower and torque. Recent dyno testing of A.R.H.’s 1-7/8″ system with cats produced gains of 32 RWHP without a tune and 50 RWHP with a tune. RWTQ was up 45 lb-ft after the tune. The system comes with everything you’d expect from American Racing Headers. This includes 3/8-inch-thick flanges with TIG welded and hand-ported inlets, merge collectors with scavenger spikes, 200 cell metallic substrate cats, OEM-style band clamps, Grade 8 hardware and Flat Out Racing Gaskets. The exhaust system is all 3 inches, and extends to the rear axle where it reduces to 2 1/2- inch I.D. and mates to the factory exhaust. Primary sizes available are 1 3/4, 1 7/8 and 2 inches. Collectors come standard at 3 inches, but can be ordered at 3 1/2 or 4 inches for race application.
