Re: Broken Muffler Bracket.

I have noticed that the edges of the various muffler brackets are 
sharp and unfinished. In an environment with lots of vibration and 
heat, cracks can start at sharp edges and burred edges. The cracks 
then propagate through the part from cyclic fatigue. I have seen 
similar cracked brackets on other cars. This is always a concern with 
high-performance jet aircraft as well. The bracket can be welded by 
any muffler shop, or any other shop with normal welding equipment. It 
may be a good idea to take it off for welding. The high current of 
resistance welding could damage the alternator or other electronic 
components. I would recommend smoothing off all edges of any sheet 
metal parts that are removed from the car for any reason. It's always 
a good policy, and makes the cars look better, and safer to work on 
with bare hands.
