Cheers, funny you should say that about the rattle! I'm getting a really annoying rattle on idle and when going into reverse and its worse when ppl are in the back. They had to take my cat back off and refit it again when I got downpipe fitted which they didn't seem to do very well I think. I haven't looked underneath the car to see what it's rattling on but I guess it is the same as yours. It doesn't stick out much but it didn't before I had the downpipe fitted either.
How much did you pay to get it fixed?
I'll try and get some pics but it's so dirty at the moment with all the crap on the roads!
