Anyone tried making or know where to buy a muffler for the copperheads to go out the back? I think this might make it quieter while driving if you could have it out the back like you see on some of the other bigger motors.

You can go to this website www.affordablegokarts.com. You can get the single or double stage header with a variety of mufflers. They will sauter them onto the header as well.

BTW, What size engine do you have and What size boat do you have? I test drove their 18hp this past weekend and I think I'm going to get it. I was pretty impressed. It pushed my custom 16X36 flat 23.2 MPH with two guys. The boat weights 420lbs.

I didn't see anything on that site for Briggs or LCT engines. It looked like mostly Honda.

Last week I emailed the Marshmellow guys to ask if they made aftermarket exhaust for the Vanguard on the Copperhead 18 and they said no.

I had also posted another thread without finding this one but never got any replies.

The website i recomended is Honda and Honda knockoffs. HOwever they do a lot of custom work. Just give them a call.
