Thank alot everybody,

I had already come up with the idea of a threaded rod but just got to the internet to check out RCU.
I am glad to see someone else already tried it, it looks like the best way to go if I keep the Tower muffler on it.
I can probably put up with the noise once its more than 10 feet from me, as long as I know the mufflers gonna
come back with the plane.

Thanks again.
