+1 The resonant frequency is determined by the length, diameter, volume, and internal design of the exhaust system. It's a lot like a musical instrument. You could attempt to mute a trumpet by wrapping but it wouldn't do any good either. Now put a mute in the bell and you change the resonant frequency. If you could interconnect the separate mufflers to get wave cancellation at 3k hz... sort of like a stock one. That would work.
