Ok, I've got a new layout with the muffler running up into the turtledeck... looks much more user friendly with regard to the radio installation.
Just a word of caution - using a long, small ID diameter exhaust tube like that may (will?) result in unacceptable engine performance. All manner of pressure distributions will occur (experience with this) which ma result in undesired back pressure issues, and there are some temperature/heat transfer issues to consider as well.
