you want some comments good and bad?
You should use normal hose for the plumbing. You can buy a spring coil thingy to slide into the hose to keep it from folding where the bends are, Ask Ernie, he uses them on his installations.
Muffler brackets are suspect.... not saying they are going to fail, but keep a very close eye on them each pre flight for cracks.
Those clamps that hold the exhaust together ( rather than using the springs Rotax intends you to use ) they are known to dig into and ruin the exhaust long term. Nothing that will be a problem right away, but in a few hundred hours of use you will see the wear they create.

I am also not a fan of how you have just a toggle switch for the ignition and a push button for the starter. Too easy for someone at a fly-in to come along and press the button not knowing what it does. I'd rather have a keyed switch, like a car, where you can remove the key when you land at a public place.
Why is the engine painted? Did you paint it? It gives me a bad bad feeling when I see engines from " Rotax experts " that come painted. Why is that you might ask???? Well, if you are a mechanic and you have a used engine in your shop to rebuild, when you have it taken completely apart for inspection, it is EASIER to bead blast the outside of the engine to restore the appearance to as new condition, than to prep and paint it. When I see a painted engine, it makes me think some shady mechanic took a old rough looking engine and inspected the cylinders and rod side play, put new rings and a few new gaskets, coated it all with a heavy coating of rattle can spray paint and then sold it to someone as a zero time overhauled engine.
Thats about it Joe.... Glad you got a bigger engine, I couldn't imagine how it flew with a 503 with all the do dad and gadgets you added to that bird, should be decent now with the 582.
I like ti paint engines that live in Florida, keeps them from corroding and turning dull gray-yuk-powdery corrosion.
Joe I am not a big fan of the gas pipe, I am sure it is suitable, just looks bad. If you have to splice in a hose section why not just use a connector and more rubber hose?

The muffler mounts, look good, but inspect them preflight and postflight, I would suspect that if they crack, they will do it at the drilled hole above the exhaust bolt.
I agree about the switch, especially when it would be unattended at a fly in. Or install a MAIN electrical cutoff at the battery, other than those suggestions, looks great, go fly and have fun! and with that engine, you won't have to skip the cheesecake after dinner

Alright Joe.
Sorry I was not there to help you Guys.
