I have a nice set of Akraprovic slip-ons that look like new with a few hundred miles. You can't even tell they are used or were mounted. Came off a 2014 SG. $330 shipped.
That's not quite the same setup. That bike has the valve system that makes it not as loud wide open and even more quiet closed. These would sound similar if you put the baffles back in to the part of the video where he has it open. Pull the baffles out like I have them, but they do come with them, it's louder than that and not obnoxious.
Moving sale price drop, $300 shipped. This is an awesome exhaust for this price. You can buy the valve system too for leaving the house early mornings and not pissing off the neighbors and wife.
