    Hi all, I've noticed that my car is sounding more like a tractor than it should. I lifted the bonnet last night and it seems to be coming from around the turbo/flexipipe. I can't see anything obvious and smurf runs as she should, anyone shed some light on it?

    could be the cat has broke up inside. when its turned off and cold see if you can give it a tap with something and see if it rattles

    yea sounds like your cat has broke up. perfect excuse to take it off and get the gubbins from inside out

    P.S I haven't forgot about the coilovers ive just not had a minute between kids in laws and 7 seaters

    if you take all the **** out the cat it will give it a bit extra go and improve mpg slightly
    what youre doing is taking away a restriction. and to be honest an older diesel doesn't really need it

    Does it still stop if you press on the exhaust?
