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 our development and customer feedback, we 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 C7’s, as well as the C4, C5 and C6 Fusion exhausts–which we 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. Our expertise here at BBE is getting the “tone” right for your Corvette, and we think we nailed this one. 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.

What’s the difference between our exhaust systems?
FUSION Exhaust – NPP Controlled Bi-Modal…Aggressive when Open, Mild when Closed
Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP C7 Corvette. On C7 with the NPP option, the butterfly valve in the exhaust is controlled by the ECU. The valve opens based on RPM and throttle position. Our expertise here at BBE is getting the “tone” right for your Corvette, and we think we nailed this one. 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.
PRT Exhaust – Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise
The Billy Boat Exhaust PRT C7 exhaust system is the latest in resonance control technology from BBE. Completely redesigned and reengineered for the C7, the system is simple in design, though more complex in theory. You can now have a mellow NO-DRONE sound at cruising speeds and a sport note when you’re tearing up the streets. It allows true straight through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber. Designed especially for the automatic, paddle shift and cars with headers, this Billy Boat Exhaust PRT system works purely on physics and adrenaline. Increases of 15 hp and 14 ft lbs over stock.
BULLET Exhaust – Aggressive Sound
Billy Boat Exhaust has created a deep, healthy exhaust note at low RPMs with an assertive muscle car roar on acceleration. Not for the weak at heart, the Bullet has quickly become the industry standard for a deep, aggressive muscle car sound on the C7. You can see up to 18 rear wheel horse power and 17 ft lbs of torque from the Bullet. Billy Boat Exhaust’s boldest tip style and configuration insures the C7 will scream ”muscle car”.
