Exhaust "Gasket, Muffler" Life?

[spoonlamp]

Thanks simon, key bit for me is -
"4 Remove the sealing ring from the end of the

silencer or downpipe assembly and discard itas a new one should be used."


Hoping someone who has changed their exhaust or this sealing ring can answer my questions.


The picture with the brass rings and silver rings - silver is obviously this sealing ring - no idea about the others...

EDIT: [Duh - brass ones must be for the top of the downpipes, wasn't thinking about that end of the pipe!]
