I bought a set of slightly reinforced ones on eBay, they were a fiver a piece so can't really complain, I'm hoping they'll arrive by Wednesday as im doing the same trip again then too. I didn't think about going for powerflex to be fair, I just wanted to get some ASAP! The one I grabbed was actually for a classic mini, but seemed to do the job. Fit nice and snugly but doesn't hold it as far up as a proper one so it's still knocking slightly. Much better than before though
I nearly had a heart attack when I was trying to work out what it was (I'm 21 so that's saying something), as when I was parked up I turned the engine on and it started making the noise when stationary. Immediate thought is head gasket/piston rings etc etc, but went and stood round the back and was obviously the exhaust hanger. Thank f***!!!
