^^^ gotta go with Gawernator on this one.
My '09 had the M4 GP slip on installed when I bought it. Sounds great at idle. Shrieks at full throttle, and is very, very loud. Like you can be heard from (quite literally) miles away. This means you are always on the LEOs RADAR. They can hear you coming from so far away, they have plenty of time to put down the doughnut, fold up their papers, figure out which way you're coming from , and get the RADAR gun out.
With the aforementioned irritation you will surely cause your neighbors -- who won't hesitate to call the LEOs and complain -- you are quite likely to find yourself with a significant detriment to enjoying your bike.
That M4 GP got me in front of a judge with a 'fix it' ticket, the second or third time the local LEOs pulled me over and got tired of giving me warnings about the noise. With a security clearance, I can't really afford to have negative press. I swapped out the M4 for an OEM complete exhaust, and have been hammering the bike nearly daily for the past 6 years. Not. One. Ticket. Not pulled over, since I went back to the OEM setup.
I can pin the throttle in any gear, without fear of getting the attention I do not desire. I can easily carry 15-20+ the posted limit, and not get a second look from any officer I pass. This has been the case, for 6+ years.
There are probably exhausts out there that can find that happy medium; no muffler at all, or a shorty muffler with a foot of glass pack on a straight through path is a cosmetic thing. Not a muffler, at all. A straight through glass pack design needs to be a couple of feet long, to have time to knock off the worst of the offending noise. The shorter the can, the more the high pitched, raspy part of the noise comes through. You don't really annoy people at idle..... it's when you run at some RPM that it gets obnoxious.
That M4 was stupid loud at anything over ~ 4K RPM. When the bike runs at freeway speed at ~6K, that means it's stupid loud all the time it's not idling. Hearing damaging, loud.
Do as you please; just expect that there will be a majority of people in your vicinity who do not appreciate your choices.
