County Corvette

How loud is it?
Through our development and customer feedback we have 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 tone would be slightly louder than the standard Route 66 system.

What controls the valves?
The butterfly is controlled by a vacuum valve, which we built and developed completely in house.  On the Z06 and the 2008 C6 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 B&B 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 if I have a standard C6?
Not everybody has a 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 accumalter, 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 ˝” or 3”?
On the Z06 the system is 3”, while on the C6 it is 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 they bolt up to my stock H pipe or my stock headers?
Each part of the 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” Fusion.

Billy Boat has combined the best of the Bullet exhaust with the best new technology to give you the Fusion System for your Corvette. The muffler tips are double walled, 4" round or 4.5" oval. The entire system comes completely polished and the result is a truly spectacular look and sound that gives this high performance sports car the look and aggressive sound which will have heads turning everywhere you go.
