Since the introduction of the dual mode performance exhaust on Z06 Corvettes back in 2006, owners have been doing this very simple mod to keep the NPP’s butterfly valves open so they can enjoy that deep exhaust rumble all the time. Since it’s such a popular and easy mod to do, we though we would make a quick video about the fuse and its location, as well as give you a couple of before and after sounds so you hear the difference.
After I pulled the fuse, I went for a quick cruise. While I like how the Corvette’s exhaust sounds with the fuse pulled at idle, I found the experience of cruising down the highway at 70 mph in a convertible with the top down to be just a little too much. After 100 miles I pulled over and quickly reinstalled the fuse. That’s why I would recommend going with one of the aftermarket solutions that allows you to turn on and off the NPP exhaust remotely.
