Re: Solution for B&B Exhaust Drone?
What Karl is describing is what was done w the C6Z. In order to reduce weight, Corvette went w an Xpipe rather than a resonator, and to duplicate the effect of the resonator, they adopted a muffler valve, the NPP. The system he described is what I now have on my ZR using a manual electrical switch to acivate the valves.
