Broken exhaust bracket advice

[nick crisp]

Are the 2 parts of the broken clamp sitting fairly snugly together? If so, you may be able to use something like chemical metal to effect a temporary repair to the clamp. If everything is sitting firmly with no movement, I would have thought that you could get away with it for a while, the worst you're likely to experience is a bit of a blowing exhaust, and probably not even that.
