Built entirely of T-304 stainless steel, Billy Boat Exhaust Shorty Headers for the C-5 Corvette are direct replacement parts for the factory equipment. Billy Boat Exhaust is the originator of the LS1 shorty header. Incorporating the correct firing order Billy Boat uses a stepped tube design with CNC mandrel bent 1.625″ to 1.750” primary tubes that are paired into a hand fabricated merge collector for optimum exhaust gas scavenging, unlike most header manufacturers who settle for an open collector. In addition to a performance increase of 15 rear wheel horsepower, Billy Boat Performance Exhaust Shorty Headers weigh 15.3 pounds…that is less than half the weight of the heavy OEM cast iron manifolds.

The Billy Boat Exhaust shorty header for the C5 Corvette was designed to blend performance and emissions. The header fits in the factory location and has been tested to meet all requirements of the California Air Resources Board (CARB).  It has been awarded EO# and is legal to install in all 50 states.
