So, you either need a sawzall and a Dremel or small grinder to clean up the cut or you'll need a hole saw bit for a drill, a drill and a couple of wrenches (9/16" ?) to cinch the clamps down.
I've seen variations of how to "get er done" one way is to cut the factory exhaust, one way you remove it and they give you a new piece to attach to the downpipe, I think flex pipe is what's used in both cases to attach to the stack.
There's only one clamp to remove the exhaust from the downpipe and I can't remember how many in the exhaust system, i cut my exhaust out but I think it can be taken out in one piece if you lift the rear end and let the rear axel droop out.
There are several vendors to buy from, some kits are "better" than others but they all do the same basic job and they should all come with the needed parts to connect and mount the stack, typically a flex pipe makes the transition
it's not rocket science and the job could probably be done in an hour or so with the most basic of tools and no previous experience.
