As you may or may not be aware the 2008 C6 Corvette is available with optional bi-modal exhaust known as NPP however this is only an option and only for the 2008 model year. Bi-modal is two exhaust systems in one. The C6 Corvette has two mufflers, one for each side of the V8 engine. The bi-modal system has two passages in each muffler with a valve that will open or close one side of the muffler for two different sounds. From the factory the NPP exhaust system is controlled by the computer to open louder side at a certain rpm. While the factory system is ok it still lacks that deep muscle car sound that the Corvette should have, and Billy Boat Performance has addressed this problem.
Why Is It Cool?
Billy Boat Performance Exhaust has developed a kit that will convert any C6 without NPP into bi-modal. The Fusion “retro” comes complete with the remote switch, wiring harness, vacuum lines and relay assembly to operate the system along with the Fusion exhaust system itself. Going on a long cruise, push the button and the system purrs like a kitty. Want to show someone who’s boss, push the button and your Corvette will roar like a Lion.
