MHP doing fine , I had to get some black foam stick on pads to keep the pipe from rubbing against the battery case, and used some double sided sticky tape to keep the silicon from moving and exposing the pipe to hit the metal.
And as far as reusing the pipe, I was not suggesting that, considdering it is probably smaller than the tubing they use for the aftermarket systems. But see first, if it is the same, than use the tip and the pipe leading to the tip, if not, than the tip that comes with the kit might fit. But I think you still might have to relocate the hanger. The only reason that I am considering replacing the exhaust is because they did not give us a full cat back system, they just simply bolted the muffler onto our existing small tubing. That makes the muffler pointless. Air flows as fast as its slowest point. You can change you whole exhaust, but if you leave one small tube, than it will flow that slow. I think those kits will fits with some mods. the only reason why they are not listed as a kit for our car is because they only list kits that are true bolt on, not ones that have to be modified.
