Today i fitted the second hand stainless exhaust i bought nearly a year ago.
Old one really didn't want to come off, angle grinder to the rescue. 3 manifold ones came off ok though, handily!
You can see in the picture the state of the original one, all sections had at least one hole!
Ooh and the winter pack is now removed too.

Anyway, all done and running nicely! Hoorah!
