The Fusion is a bi-modal exhaust system, meaning it has two passages, or modes, that the exhaust can travel through the muffler. Each muffler has two outlets, with one side having a butterfly 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" straight through tubing .

The butterfly valve is controlled by a vacuum valve, built and developed by B&B. 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. Factory exhaust can be very quiet, even with the valve open on factory mufflers. The experts at B&B worked hard to get the "tone" right for your Corvette. In the closed position, the tone is deeper, louder, and more aggressive than stock, similar to the Route 66 systems. Open the valves, and the overall volume and tone increases to the point heads will turn when you drive up, similar to the famous Bullet systems.

The Z06 system is a full 3" and can be combined with a B&B Performance XPipe (optional) for even more exhaust flow.

The muffler tips are double walled, 4" round. 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. All B&B products are precision built, completely TIG welded, and are a direct replacement for stock exhaust components including all hardware and gaskets. A perfect mix of performance, sound and style for the Z06 Corvette. Each Billy Boat Performance Exhaust system is backed by a lifetime warranty against rust, corrosion or burn through and 2 full years against defects in materials or workmanship.
