Thinking about Electric cut outs

How's this for "Off-the-Wall" thinking? (sometimes I scare myself)

You have a killer motor that moves the earth through 3" 2-chamber Flowmasters so you
use the electric cutouts in reverse. When closed, the exhaust is channeled through a couple
of very small quiet mufflers - just for idling stealthily into the drive-in or pulling out past
the cops. Once free and clear, go back to the big system and let 'er rip.
