1997-2004 Billy Boat Fusion SS Exhaust System with Quad 4.5 Inch Oval Tips

The Fusion is a bi-modal 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 exhaust flows. 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.

The butterfly is controlled by a vacuum valve, which was built and developed completely in house. On the Z06 and the 2008 C6 Corvette with the NPP option, this valve is controlled by the ECU. The valve opens based on RPM and throttle position. Since the C5 Corvette has no option for the valve, we use the same vacuum kit and control as the C6 without NPP. The expertise at B&B is getting the "tone" right for your C5 Corvette, and we think they nailed this one. In the closed position, the tone is agresssive, but substantially quieter than the standard Bullet system. Open the valves, the overall volume and tone increases to the point of the classic Bullet exhaust tone.
