Well, the plane is running great, but it's a little on the noisy side, like I mean a lot. I removed 7 disks from the SuperTrapp and retested it. Much better with no noticeable power loss. Tomorrow I will remove 2 more disks and see how that sounds and performs. One fellow removed all disks, packed it with stainless steel wool, and welded a stainless steel pipe and downturn to the baffle assembly. Kind of like a glass pack muffler. That could be in the future, if all else fails.
