Billy Boat Exhaust axle-back for the 2017-2019 C7 Grand Sport Corvette with a manual transmission and 2015-2019 C7 Z06 Corvette features high grade 304 stainless steel for the finest system integrity with speedway tips. Billy Boat Exhaust has combined the best of the Bullet exhaust with the best technology from the factory to give you the C7 Fusion Exhaust NO-DRONE System for your Corvette. Utilizing the same exhaust control valve as the factory system, you get a "Dr. Jekyll" cruising sound, and release the "Mr. Hyde" Bullet Exhaust sound when you want!

How loud is it? Through BBE's development and customer feedback, they have shortened the muffler, making the loud side of the muffler louder, which results in a tone similar to the famous Bullet system. In the closed position, the tone would be slightly louder than the standard Route 66 system.

What controls the valves? The butterfly is controlled by a vacuum valve for non-NPP C7s, as well as the C4, C5 and C6 Fusion exhausts which BBE built and developed completely in house. On the C7 with the NPP option, this valve is controlled by the ECU. The valve opens based on RPM and throttle position. The problem is the factory exhaust is very quiet, even with the valve open. 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.

*Add the FCOR-0468 conversion kit for Corvette models without factory NPP controls. The kits comes complete with all the wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch needed for installation. Can only be ordered with Fusion Exhaust Systems.
