09-13 w/NPP B&B Fusion Exhaust System - 4.5" Oval Tips
The BBE 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 exhaust flows through. 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 BBE Performance Exhaust. On the 2008 & later C6 Corvette with the NPP option, this valve is controlled by the ECU (computer). 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 BBE Performance worked hard to get the right "tone" for your C6 Corvette. In the closed position, the tone is deeper, louder, and more aggressive than stock. 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.
What if your Corvette does not have the factory NPP option - but you'd still like to have the bi-modal exhaust? BBE developed their own retrofit kit which allows a non-NPP Corvette to utilize bi-modal exhaust. The kit everything needed for the conversion; controller, vacuum hoses, control switch, and instructions. See mcc # for the Fusion retro control kit. Note: This kit is NOT required on NPP equipped Corvettes.
The 2009-2013 Corvette system is 2 1/2" and can be combined with a BBE Performance X-pipe (optional mcc # ) for even more exhaust flow. The muffler tips are large oval 4.5" diameter double walled and polished - the rest of the system has a satin brush finish - and the result is a truly spectacular look and sound that gives your Corvette the look and aggressive sound which will have heads turning everywhere you go.
All BBE Performance exhaust systems 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 C6 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.
