My car let me down at the weekend, with the "bong of doom" for suspension roll, and a puddle of oil in front of the rear left wheel, so I'm assuming that this is the rear ACE pipe corroded through. As far as I known, these are the original 12 year old pipes.

I can't replace the pipes myself, so I'm going to have to pay the labour for someone else to do it, and I know it's going to be substantial. If I'm paying all that money, is there anything else that might make sense to change "while they're in there"?

I believe that the rear heater pipes might be a candidate. What else?
