Corvette C6 Fusion Exhaust
Billy Boat Corvette C6 Fusion Exhaust with Quad Round 4" Tips for the Corvette C6 2007-2008 with the NPP Multi Mode Exhaust Option.
What is bi-modal exhaust?
The Corvette Fusion Exhaust is a bimodal exhaust system, meaning it has two passages, or modes, that the exhaust can travel through the muffler. Each of the mufflers has two outlets, with one side having a butterfly type valve which allows the exhaust flow to be shut off, regulating which side of the muffler the flows exhaust. One side of the muffler is the quiet side, and one side is the loud side. The quiet side is a smaller, muffled and chambered tube, while the loud side is 3" tubing straight through.
How loud is the Corvette Fusion Exhaust?
Through our development and customer feedback Billy Boat has shortend the muffler for 2008, making the loud side of the muffler louder, which results in a tone similar to the famous Bullet system. In the closed position the Fusion tone would be slightly louder than the standard Route 66 exhaust system (good for highway cruising with minimal to no exhaust drone).
What controls the valves in the Corvette Fusion Exhaust?
The Fusion exhaust butterfly system is controlled by a vacuum valve, which was built and developed completely in house at B&B. On the Corvette Z06 and the 2008 Corvette C6 with the NPP option, this valve is controlled by the Corvette's ECU. The valve opens based on RPM and throttle position. The problem is the factory exhaust is very quiet, even with the valve open. Billy Boat's expertise here is getting the tone right for your Corvette, and they think they have nailed this one. Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves and the Fusion's overall volume and tone increases to the point heads will turn when you drive up.
What if I have a standard Corvette C6?
Not everybody has a Corvette Z06 or the 2008 with NPP, right? Billy Boat Performance Exhaust has spent months developing a stand-alone kit which allows any C6 to take advantage of the bi-modal system. The kit come complete with all the wiring, mild-to-wild switch, vacuum line, vacuum accuator, and vacuum switch needed for installation. We have used the engine as the vacuum source (it is the same port the factory uses for the NPP) and the installation is simple and straight forward.
Is the system 2 1/2" or 3"?
On the Corvette Z06 the Z06 BB Fusion System exhaust system is 3", while on the Corvette C6 it is 2 1/2". We do have an x-pipe available for both systems, and the standard C6 can be ordered in the 3" diameter to make a complete 3" system.
Will the Corvette Fusion Exhaust bolt up to my stock H pipe or my stock headers?
Each part of the Fusion Exhaust system will fit to a stock H-pipe or the stock headers. The parts can be mixed and matched (rear exhaust, x-pipe, and long tube headers) For best performance it is recommended to use the long tube headers, the 3" x-pipe, and the 3" Corvette Fusion.
