New Muffler tech....
 

I wonder if this will make it's way into mufflers at some point?

SOUND CANCELLING SHAPE

Interesting!

And they will make it rich. law makers I mean nazis will eat this right up. Back to a horse I go.

No thanks, I prefer to "hear" my exhaust else I would buy a fuckin' electric-mobile.

Same here I want to hear it or Id play a video game and save a lot of money.

Good one cruisin.; how you doin' these days?

It just blocks one frequency, (or a very narrow range) so it would take several dozen I suppose to block most of what comes out of an exhaust.

Sound-cancelling technology is well known to every automobile manufacturer.

Does it cancel mouth-noises?

:lol:

You want one for "the wife"?

one is already sold likw that. No noise. its called a Prius. I like the sound of a nice cammed up corvette.
