My point exactly, except with a 3-speed I can change ratios on the fly with the twist of a wrist and not have to remove the whole wheel and change sprockets and chain size to change it ;-}
Not sure I like the idea of a 1" straight pipe,besides being loud and messy you don't get any expansion chamber 'reverse turbo charge' benefit.
