I've got a snap on one that is more useful than I could ever have imagined

Ok so here is another update... So I was running the ski yesterday and I changed waterbox back to stock. It was running great mid to Topend. I noticed it had a lot more power up top! When we got back to garage to flush the exhaust had vibrated loose( APE EXHAUST). Now I know these are notorious for doin that so I used threadlock on every bolt( blue). It still came loose. I even used NEW ss lockwashers. Crazy thing is that it ran STRONG! So here is my question...

Should I use RED thread locker?
Any other ideas on how to keep this exhaust together?
If it ran strong with exhaust fumes in bilge does that mean that I need to lean it out? I'm thinking the exhaust fumes leaned it and therefore the strong running. Hmmmm.....

Spitballing ideas here..

What about more exhaust==> Less oxygen==> Richer?

Try running with your high speeds turned out some more? Always go rich to see if it improves first?

What do your plugs look like now? From the look of the previous pictures, it looked a little rich as you suggested.
