Sure. I would send pics, but RCU won't let me. Maybe I have to be a senior member. Anyway, the problem is the Can is too long. Getting under the Wing tube is very tight. And because the header does not have a drop in it, you have to angle the can down, therefore resulting in the rear of the can sticking out the rather large hole you have to make in the bottom of the fuse. So the last 2 or 3 inches of the can sticks out of the fuse about 1/2 inch. Does not look nice. Also this means that the Teflon tubing is bent at an angel and I am told this might not hold up. It is interesting that in all the pics of the DA and can installation in the 2x2, show the hole in the fuse, before the can is installed and only show the can installed in shots where you can not see the area I am talking about.
I worked with DA and they were very helpful but did not currently have a solution.

CA says they fly the 2x2 with this setup ?

So in the end it does not look good, the can is almost touching the wing tube and the Teflon connector is bent.

I will be test flying my 2x2 this weekend. I guess we will see how it works.

You might want to consider a Pitts style exhaust. Not sure it would work but there has to be a better solution then this.
