Interest was expressed in my exhaust system so give I'll it a go...
I pulled the stock boat anchor off and observed the square pipe welded to the flange at the exhaust port was way SMALLER than the ex port on the head. My way of thinking is that just ain't right so decided to build the mess you see in the pictures.
I'm one of those guys that builds everything I can from whatever old junk I have around and this setup could have looked way different depending on whats in the junk pile.
Laid out my "origin unknown" shorty mufflers and figured where the pipes had to go. Couldn't come up with any u-bends tight enough. So made my own out of 90 degree pipe. Don't remember the size but it is the SAME diameter as the port in the head. I could go out and measure it if anyone cares. If I was to do it again I would get some pipes and maybe some mufflers also from a motorcycle wrecking yard. Some old dirt "scrambler" bikes had high pipes with a tight bend. Plus CHROME plating!!! That would be really cool!
Finding a muffler short enough to stay out of harms way might be a problem. I gas welded it all into one solid unit. Mounted the rear of the muffler with some of that flexible canvas type stuff they hang tail pipes with so vibration and movement for heat etc didn't break things. Been on there maybe 50 hours and holding just fine.
The rear bumper was really just a way to mount the mufflers and protect them. Just happened to have a hunk of steel the right length. Could have done it some other way just as well. Whatever works.
The round chrome thing on the engine shroud is an inspection cover. Had those little snap in things laying around so used a hole saw and presto I can see if there is any grass building up in the cylinder fins. Or at least I hope I can see where the grass builds up. Not 100% confident I can but I think so.
Behind that little triangle white paint is my gas shutoff. I use a tube with slots in the end to reach in there so I don't have to lift the eng cover. Man I'm lazy in my old age.
