If you are one that desires to keep your C6 adorned with only GM factory parts and accessories, then the ultimate upgrade for your exhaust has arrived.
Newly available, the NPP OEM vacuum assisted exhaust gives you the famous Z06 sound on any Corvette C6. Each order includes a pair of GM mufflers with the butterfly assemblies.
If you don't already have a control system for the vacuum you will need to order the retrofit system above with your order. The activation of the butterfly valves will be controlled manually with a remote control.
