    Curious muffler question

    I really wonder about this....at the very front of my mufflers (both sides), where the 2 exhaust pipes merge into one and are connected to the mufflers.....there's a perfectly round hole ( on the underside) a little smaller than a "BB". I thought it was a problem that should be welded until I noticed it's perfectly round and is in exactly the same spot on both sides....is it supposed to be there????

    Thanks, guys!

      the pipes on your bike (and most of ours) are double wall pipes, there is a pipe inside the pipe you see.
      this was done so the chrome on the pipes would last longer than the first time it was run.
      the hole is a drain hole to allow water that finds it way into the cavity between the pipes, to drain out.

        Thanks, so much, guys....I try to offer help on this forum, when I can, but I feel much better about my own questions when I hear from real experts!
