ARH - Long Tube Heads & X-Pipe Long System (2010+ Camaro LS3/L99)

For the 5th Generation Camaro, ARH has what you need to exhaust the beast within. Our 100% U.S. made Long Tube 304 S/S header systems are designed to fit great, install easily and produce outstanding horsepower and torque. Dyno testing of our 1-7/8" system with cats produces gains of 32 RWHP without a tune and 50 RWHP with a tune. RWTQ was up 45 ft. lbs after the tune. The system comes with everything you'd expect from ARH: 3/8" 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 Flat Out Racing Gaskets. The exhaust system is all 3" and extends to the rear axle where it reduces to 2-1/2" I.D. and mates to the factory exhaust. Primary sizes available are at 1-3/4”, 1-7/8" and 2" Collectors come standard at 3" but can be ordered at 3-1/2" or 4" for race application needs.
