I have mine pointing straight back about one and half inches from the floor of the cockpit. I get a drumming in the cockpit which I'm told is from my exhausts (and black exhaust marks on the paint). In the next month or so I am going to get 2 bends, 60 degrees, and clamp to the exhaust pipes to see if this fixes the problem. I'm going to the hanger this evening and will take some photos of the exhaust.

But if you don't drop them a couple of inches it will burn paint and blow black on the belly. I had mine come out at the back of the cowl at an angle. Then I cut the exhaust so it would blow towards the back ----- Original Message ----- From: "Donald Reid" <donr...@peoplepc.com> To: <kr2coo...@earthlink.net>; "KRnet" <kr...@mylist.net> Sent: Wednesday, January 26, 2005 6:59 PM Subject: Re: KR> Exhaust > At 04:10 PM 1/26/2005, you wrote: >>Are there any rules of thumb of scientific formulas that would determine >>the length that the exhaust tubes should extend below the belly of the >>airplane. > > If at all possible, the exhaust should not extend beyond the surface of > the > plane.
