Dave,

nice inverted installation. I actually didn't think the cylinder would fit without being exposed at the sides. Works well with a pumped YS.

I think Joshua was considering (or maybe I had hinted at it) an inverted installation with an enclosed pipe and an S shaped header bringing the exhaust up to the top of the fuse. This is what I was recommending against in a T720 but all kinds of Tipo's have been built.

With an inverted installation and the pipe under the wing, it works out more or less like a side mounted install does.

David.
