Not a whole lot of change in the f but with a little duct tape and a bigger hammer I'm sure it can be done.
I'd go with a D&D just try to stay about the same length other wise they sound like a Kohler lawnmower engine. The D&D carbon is a shorter muffler though and it sounds pretty beefy
You just need to buy the one integrated taillight. It'll have two extra wires that connect to the turn signal wires.
