Thanks, Matt, and yes I fully expected the need for the pipe.

Someone asked before, but which soft mount is that in the photos of your Enigma, and which prop and header are you using?

No rush, so I will wait and read about it in K-Factor if you don't want to divulge more at this time. I was disappointed when reading about the less-than-ideal results with the ZDZ 40 and am very excited that I might have a reasonably-priced 2M that doesn't gulp $30/gal fuel![8D]
