If your tallking a Fast M-10 I put one in an 08 Dragon with no problems. If you think you will turbo down the road though you might want to reconsider if you go with a kit that dumps in the tunnel behind the chain case. The M-10 front mounting bracket does conflict with the turbo exhaust.
If I'm on the right track with your question and you have any others, let me know, I have some good pics from the install. Good luck. EW
