Resonator Only, or with Muffler Too??

I have been reading the threads on 273 exhaust. Am planning on installing the commando single exhaust; mostly purchased from Accurate Ltd. I have read in a couple of threads that going with the resonator only (no muffler) sounds great. From what I have read, some of the early Commando 273's came that way from the factory (?). I want the car to sound good, loud is fine, but not too loud.

Thoughts?
