Billy Boat Performance Exhaust, the originator of the LS1 shorty header developed these headers as a direct replacement part for the factory equipment. Precision crafted entirely of T-304 stainless steel, the longer, equal length primary tubes increase performance and throttle response.
Incorporating the correct firing order the CNC mandrel bent 1.750” primary tubes 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 10 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.
