Anyone fixed the breaking exhaust springs (3) recommended replacements etc please ?

I have a write-up in the How Tos on spring replacements I did on the Z. I used Moose springs but the length is important..and CFM systems take several different lengths.

These seem to take 70mm ones. we have replaced a lot in 600Km and we have 11 vehicles, well, 10 at the moment as one trashed its rear left disc seals. trying the ones with separate hooks.

I was surprised to see that I was able to cut and re-bend a hook on the CFM springs so easley..but it also seems that once they get hot they loose some of their temper and stretch again. No issues with the Moose. 

Fitted thicker Sasumi 70mm springs, none lost so far.
