Bracket for holding silencer
My brackect for holding my silencer snapped today. Temporarily, I've made one the same but I want to make a proper one.
The ali strap that I used first of all fractured at one of the bends. I have bent the new one witha larger radius but maybe aly is not the right
material to use. What should I make it from and where can I get a small piece?

mild or stainless steel i guess, an exhaust will always wobble which will lead to work hardening in ally.
Beware! Bourettes is binfectious.

Might be a silly question but was it solidly mounted to the car, or was it on rubber mounts?
Should imagine if it was on small rubber bobbins they should flex instead of the ali

I used ali and it's been OK so far. Mounted on a Land Rover engine rubber mount:

Stainless is going to be much stronger than ally but more awkward to bend depending on the shape. Either way, rubber mounting is essential.

It's not on a bike engined car, as the engines bolted in solid anyway.
Things with engine mounts made of flexible material need a flexibly mounted exhaust.
Usually.

wot he said 
Apart from that, if you want to keep any tooth fillings you may have, a rubber mount is a good idea. It also acts as a buffer for vibration induced
noise.

It is mounted on a rubber bobbin. I might try a bigger piece of aly but stainless would be nice as I have a stainless exhaust. where can I get a
strip of stainless from. Is it easy to drill? I'd heard that it was very hard.

this is my set up;
 
rear exhaust support
It has no history hence I cannot comment on suitability/longevity. One thing I plan to do is to weld a steel strip on the inside for the top bolt as
it is held to the side panel - I suspect that over time that will fatigue hence the additional support inside plus the side panel will not act as a
vibrating diaphragm.
Don't want to build your hope up but I may have some s.steel sheet at home that I could cut a short strip - chances are it will be too thin for
your needs. If you struggle, B&Q do mild steel strip, 2mm thick, various widths for a few quid that would do just as well (just need painting).
