What does the engine bay space look like further down from the top surface? I'm sure you have a good grasp of the geometry but I can't see how much room there is between the LS and the crash bar. If a notch in the crash bar is all it takes to get a healthy Y-pipe fitted, that'd be worth it.

They do make a water repellent outerwears for jetski flame arrestors/marine applications. Iirr, you can get a sheet of it. Could secure it to the bottom of the deck lid opening, then secure another piece to the airbox/filter,,, that might be enough considering how much distance is between the filter and deck lid opening.
And if you could design in the deck lid a 'channel' like the convertible tops use with drains, on the bottom where the outerwears is secured to the lid opening, so water doesn't puddle on the outerwears screen that might help... Might need to use more of an angle to help gravity drain off the water into the channel...

Does anyone make an aftermarket TB that isn't quite so gigantic?

I was looking into it a bit the other day, but it seems the actuator is mostly in line with the axis of the butterfly plate. I saw a couple that looked like the actuator was behind the axis a bit, but nothing promising.
This was the closest I found, at ~$750ish but totally bling.

I have a y-pipe from a 997 turbo that I will donate if needed....

Not sure if its too big or too small. I can measure the TB side if you'd like

Yeah...it's quite close with a 4" tight radius silicone elbow. I think that's all that would fit.

Actually.... @theprf I think you're onto something. A quick comparison between the two throttle bodies looks like, if I spend some $$$ on the bling TB above, I'd have room for a Y splitter. I wanted to avoid a Y splitter, but I think it would work well enough.
