Billy Boat Exhaust axle-back for the 2017-2019 C7 Grand Sport Corvette with an automatic transmission and 2014-2019 C7 Corvette utilizes the same exhaust control valve as the factory system for a "Dr. Jekyll" cruising sound and "Mr. Hyde" Bullet Exhaust sound when you want! Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.
Required: Add conversion kit FCOR-0468 for Corvette models without factory NPP controls. Kit includes wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch.
