Right enough. But rather than "replace" the sound with "something nicer",
the Right Thing To Do (tm) is to use the active muffler in the manner
of a header/expansion chamber - in other words, to Make More Power!
Pretty much for certain this won't help the "noise" emissions, but
maybe you could use a "two-stage" active exhaust system to mitigate
the increase in sound...
