I'm in the market for a new can myself. I've looked at Micron, Hindle (highly recommended for Honda), Akrapovik, M4, and Devil Systems. My preference is for a high mount system where I'd like to retain my passenger pegs, but it's not an absolute necessity.
Micron high mount aluminum is about $327 @
www.parts411.com. The Micron website has the different colored cans to match your bike @

Hindle slip on aluminum muffler runs about $209 plus $54 for the slip on tailpipe you'll need to add to your OE header in order to put on the Hindle slip on muffler. Most complicated of the bunch. Don't know why they don't just sell the parts as one unit.
Akrapovik doesn't come as a high mount so I'd have to purchase an "S" pipe separately and modify it--that would run about $499 plus about $70 for the pipe
M4 high mount aluminum system will run about $250. The least expensive high mount system without modifications (extra "S" pipe,
Devil Systems
retains the passenger pegs plus gives you a unique dual high mount muffler look for $419 (aluminum high mount) or $449 (carbon fiber high mount)
You can check out each exhaust system by visiting the manufacturer website or

I like all the systems, but have narrowed it down to Micron or Hindle....and maybe Devil. We'll see.
Good luck with yours and once you decide and have one mounted, be sure to post a pic and sound clip.
Cheers!
