Quiet aftermarket exhausts?

So I have a 09 xt660z I have kevs fuel and o2 mods and a dna stage two filter on the way, the question is will I see any noticeable difference in performance by fitting an aftermarket exhaust in which case are there any systems out there that won't obliterate my eardrums and shatter the neighbours windows?
Thanks in advance Rich.
