I've got a new one coming...
seems to be.
Remove rear bumper
Loosen bolts on bottom of dampers
Jack up rear (HIGH!)
drop rear beam (disconnect dampers)
Undo all mounting points
Remove exhaust (poss flip it upside down to get it out)
Fit new exhaust - exhaust sealant around cat clamp
Line it up
Tighten it up
Put it back together - will involve dropping car to right height to reconnect dampers i expect.
Or.... cut exhaust (prob with angle grinder) then you don't have to worry about getting it high, bumper and dropping the beam.
I'm jsut waiting for mine to arrive - car off the road for 2 weeks so far
