I have a off road style go cart, and its fun as hell. But its also loud as hell, and Massachusetts is probably the least ORV friendly state. I need to quiet this thing WAY down so neighbors don't call the police (which they will now, im talking suburbs). I took off its stock muffler today and i could definitely chop its apart and basically turn it into a mount on which I could mount some other muffler. So the question, where can I get something that will quiet a 6.5 HP singe cylinder motor. I've actually thought about putting a car muffler on there but they are just too big. I need something smaller, but that quiet would be nice.
