I would suggest stopping by Miller's Custom Parts in Daytona. See Arnold there he can help you with picking out the exhaust, installing it and going from there.
On my 2011 SERGU I went with the Kuryakyn Package. I did not need to buy the air cleaner with the perfect storm so I saved some off the 1686.00 list price.
The package includes the headpipes, the mufflers, the air cleaner, as well as a TTS and they have maps already for you so you don't exactly have to have a dyno tune unless you want it perfect. I have done this on 3 bikes 2 with true duals and 1 with the power chamber 2 into 1 into 2 and the VH High output slip ons.
The kuryakyn pipe is the same as the VH power chamber except for the plate that covers the power cell area itself. Can ride all day and not get off the bike with ringing in my ears, yet it has a low deep rumble and cars hear ya. If you need a listen to either of the systems shoot me a PM and we can meet up.
