    Looks like I have a hole at the mount on the fat part of my Dyna pipe, got home and notice spooge leaking from a 'new' area...I have yet to remove clean and inspect, which i'll do today. I did notice performance fall off on my last loop of the day, it stumbled on 0-50% throttle and wouldn't idle that well, would these be symptoms of a small hole in pipe?

    thanks,
