Here is a an explanation of the "muffler mod' for the NPP exhaust of a C6 Corvette (a Z06 in this case). Isaac and I will talk about the modification, walk you through the steps, and show before and after footage. This is a great mod for anyone looking to make their car louder while maintaining the valved capability and not breaking the bank.
