I had a friend that done this on a 700raptor. It gave it more power and sounded unique. He had a modified yosh exhaust on it, They are fuel inected but he had it tuned and it ran perfect. I would do it. Trial and error if anything. Just make sure you get the fuel -air intake set up for the exhaust.
