Stress crack!!! Stainless is very funny about heating and cooling in an exhaust situation. As it heats and cools it becomes work hardened and very hard, with the hardness it also gets very brittle. as you run it it wiggles and vibrates then after some time Bang!!!!!!!!!! there you go. That is the reason why most bikes and cars have lots of hangers in the exhaust system especially out on the end where it will move allot.
The only way to avoid this would be to add a brace to keep the wiggling down

Vibration. When you take that engineered pipe out of it's intended application and use it where it is subjected to different stresses it will break. A motorcycle exhaust is designed to be as light as possible and still get the job done so it doesn't have much tolerance for increased vibration or different support arrangements.

petri and JD have nailed it...I would like to add that motor cycle muffs. are made with fairly thin metal .. and YES Brackets

I think everyone has pretty well explained it. A bikes exhaust is not made to be mounted like that with the weight pushing down and the vibrations.

I've posted it a few places and it always seems to be lost, so I put it up on my own website where I know for sure it won't be lost.
Here's a link.
