Big block muffler
Any recommendations for a budget conscious, simple, quiet muffler? I picked up a new cart this week and it’s awesome but you can’t talk to the people right next to you.

Re: Big block muffler
What engine are you dealing with?
Most stock mufflers that come with the engines today are decently quiet, and are sound rated to meet epa requirements etc. With a bigger engine, sound always going to be louder than a stock golf cart. I have experimented with several mufflers for my past projects. The one that I liked best is a universal tractor muffler found at any tractor dealer or supply. I have also used factor atv mufflers and they sound pretty good, like an atv. |

Re: Big block muffler
I bumped my thread on clone exhaust. You can see what other have tried on their cart. Even if you are using a Vtwin this should give you some direction as they seem a little easier to quiet down.

Re: Big block muffler
Thanks guys. Sorry, it’s a Honda vtwin. I bought it and have words every day since so I just started messing with it. The header has a leak which I think is why it is really really loud:)

Re: Big block muffler
I found an old atv muffler that made a huge difference in sound. The old exhaust was way to loud for the neighborhood going down the road. (late at night) This is on an 18hp vanguard, the muffler was just slightly bigger than the header pipe.
The last pic is a pic of the old exhaust I was using. Now you just get the motor noise. Exhaust ($10.00) from atv mechanic in town |

I am not sure of the engine size from the atv, but the pipe was slightly bigger than the exhaust on the vanguard. That is what the atv mechanic was concerned with. He didnt mention the engine size. Whats your thoughts on that? |

Re: Big block muffler
Well, the pipe size is not the only factor. Inside the muffler there is a silencer/spark arrestor that usually chokes down the size a bit. As long as it runs good it and it's quiet enough, it really doesn't matter. Quiet is important too.
