From what I can tell (and the 2bros exhaust that came with my Vee), you don't have to touch the head pipes. The only systems I see on their web site are slip-ons.
There's a clamp on each side about where the exhaust passes the swingarm, then a bolt through each passenger peg and one mounting bolt on each side.
A half-hour, one-beer job, tops.
Then you'll need to install and retune with a Power Commander. That will probably take longer.
Keep the stockers around for a while... all the 2bros stuff I've heard is louder than the very hammers of Hades. Even with ear plugs, a pounding headache is guaranteed with every ride.
