Looking for the quietest exhaust available for my 2013 King Quad 750 I just picked up. Trying to be a good neighbor while I plow my driveway. Any suggestions/advice would be much appreciated.

 

The stock exhaust for the King Quad is fairly quiet unless the tin shrouds come loose which rattle like mad or if the tubular seal between front pipe and silencer (muffler) lets go. This is common and makes the exhaust very loud.

 

I never heard a ATV that is louder then a snowblower, your neighbor should be so lucky your not using one of them instead.

I know of deer hunters who like their ATV more quiet then stock. Here two companies that makes them. "Kolpin" and "Silent Rider "

 

I'd just leave the stock exhaust on. Yes, these silent rider exhausts probably will make it a bit quieter but they don't improve performance and buying something that doesn't improve the machine seems like a waste of money to me. You're just bolting on an extra piece of metal to dampen the noise, probably actually costs you a couple hp. Unless you're plowing your driveway late at night, I see no need to make your stock exhaust quieter.
