The video clip you are about to see is of a 2008 C6 Coupe Corvette with our RXx-1 combined with a our Magnuson supercharger system installed. This C6 has a Corsa muffler system on it so the sound is a little louder. This Corvette makes over 700HP at the engine. To make this HP level we have added our Blower system upgrade package with it. It includes a custom pulley size along with tuning and gauge package. Like what you see and want one? Give us a call. Enjoy.
