Billy Boat: 1-7/8″ Long Tube Headers [C7 Corvette LT1]

Billy Boat Performance Exhaust has once again taken the Pole Position in the market by developing long tube header systems specifically for the C7 Corvette. The header design incorporates the correct firing sequence which pairs exhaust ports together for more efficient exhaust scavenging. Dyno testing, utilizing technology previously found in racing applications has shown an increase of horsepower and torque throughout the entire RPM range. This is a true bolt-on header, complete with hardware and gaskets, dedicated to the C7 Corvette. The 1.75″ tube flows seamlessly to a 3″, 4-into-1 collector. Billy Boat Performance Exhaust also makes a variety of x-pipes for the c7 Corvette.

The 3″x-pipe section evens the exhaust pulses with a synchronized crossover in the center section, resulting in a deeper, smoother tone.
