Quiet Muffler?

[GoKartGuy123]

Anyone got some advice on quieting down their karts? Would like to add maybe a second muffler on the back of the existing or fab up a new one.

Anyone try this?

For example, I've welded a car muffler to my atv's in the past and basically eliminates the thump out of the exhaust. It's big and bulky but nice for not ****ing off the neighbors in the morning.

use a 1" OD exhaust header and then just put a honda grom muffler on it. The muffler wil bolt up to the end of the header with ZERO modifications. You can get a honda grom muffler for about 40-$50 on ebay and it is super super quiet. Other mufflers are available but cost just about as much and are still pretty stinkin loud. see example here:
