The Grand Sport Registry (GSR) is proud to make available a new, improved version of the popular Mild 2 Wild Exhaust Control for all 2008-2013 C6 Chevrolet Corvettes which were factory equipped with GM's optional Dual Mode (NPP) exhaust system. Mild 2 Wild is the original FCC approved wireless system which gives you full control over the exhaust sound of NPP equipped Corvettes. Fits all C6's with NPP Exhaust including Z06, ZR1 and Grand Sport. It requires no drilling or running wires through your car. The included fully illustrated instruction card makes it a simple 10-minute plug and play installation anyone can do from inside the car. You don't even have to open the hood! It can be just as easily removed at any time The kit comes with TWO sleek wireless key fob sized remotes that will control the exhaust up to 50' away. The "OFF" mode gives you that race car sound 100% of the time. The "ON" mode reverts back to the car's stock setting and keeps the exhaust in quiet mode until the OEM factory preset of about 3,500 RPM. The remotes can be used anytime the car is running, inside or outside the car, allowing you to show off your exhaust by opening and closing the exhaust valves on demand. For added convenience, you can program your driver visor vanity buttons to control the M2W exhaust! This new improved version features an internal antenna making installation that much simpler with no need for an external wire. Plus we also include self-adhesive mounting pads and cable ties for your convenience. Please note that M2W does not work with the standard (no valves) exhaust, aftermarket systems or non-factory installed systems.
