Having recently done my annual permit servicing I noticed that a clamp
had come detached from one of the straps which hold on the heat shield
for the silencer. On closer investigation I found that two of the four
corners of the heat shield had cracks and one had lost a corner of the
shield entirely. This exhaust system had only been fitted for one year
and a total of 55 hours running. I replaced the heat shield. Both the
old and new shields had sharp corners and sharp edges. I have rounded
these to reduce the risk of future cracking. The exhaust manufacturer
has been notified suggesting this is done on future exhausts before
dispatch. Other XS owners with 912's may wish to check their heat
shields.
