Kitfoxers. Looking at a closeup of a Bluehead 582 engine installation Bill Chenoweths), I see the exhaust manifold is installed angled down with the EGT sensor mounts on the bottom. I swear when I received my used engine the manifold was mounted angled up with the EGT probe mounts up. I have reinstalled the engine and mounted the pipe and muffler. Fits fine with probe mounts up. And looking at it, I believe if I flipped the manifold over the pipe/muffler would be too low to bolt up. What gives? Were some engines installed with exhaust manifold up and others down? I sure hate to remove mine with all the springs saftey wired already, flip it over and find I am right and the pipe won't bolt up.

has anybody ever figured out how much power is lost or the effect it has on accurate egt readings by chopping the elbow and muffler?

Malcolm,
I extended my muffler back to Rotax specs and saw no effect
whatsoever, EGT or otherwise. I couldn't fix the elbow because I
didn't have room. I'd love to make a custom exhaust, but just don't
have the tools to make nice expansions with curves.

I like it fine Pat. Makes a big difference at idle, alot less shaking. The thought of an engine-out situation and resulting free-wheeling prop freaks me out a bit, but that topic has been beaten to death here.

I got to assume you are talking about a 582... Well it will kill your power. The elbow and the piece actually going to the muffler are what is called and expansion chamber. It causes a sonic barrier inside the chamber that sort of acts like an exhaust valve. This is why different pipes can cause the engine to produce more power but usually it will also cause the engine to get very peaky where maximum power and torque are in a very narrow power band. This si great for bikes but has no place in planes unless you are doing short take off contests all the time.

That wouldn’t be a calculation but a dynamometer test. If you really want more power just drop in a snowmobile exhaust... You will get more.... power and heat and less power band.
Apparently the original Rotax exhaust is slightly longer than the Kitfox one. The Kitfox expansion chamber had to fit inside the cowl. That will cause a modest reduction of power If you wanted to you could make a blister on your cowl and put the longer expansion chamber on and gain maybe 5 hp without making the engine too peaky.
