Chevy C6 Corvette Fusion Axle Back Exhaust System for factory NPP. Inc Grand Sport. (Oval Tips) #FCOR-0559

Billy Boat has combined the best of the Bullet exhaust with the best technology from the factory to give you the C6 / Z06, C5 and C4 Fusion Exhaust NO-DRONE System for your Corvette. Utilizing the same exhaust control valve as the factory system, you get a “Dr. Jekyll” cruising sound, and release the “Mr. Hyde” Bullet Exhaust sound when you want!

How loud is it?                                                                                                                                                                                 

Through our development and customer feedback, we have shortened the muffler, 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 for non-NPP C6’s, as well as the C4 and C5 Fusion exhausts–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.

*Add our FCOR-0468 conversion kit for Corvette models without factory NPP controls. The kits comes complete with all the wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch needed for installation. Can only be ordered with Fusion Exhaust Systems.
