alright lads i changed the cat on my leggy today on the advise of my mechanic, it was knackered and there was a fierce rattle of it whilst driving.....a head wrecking rattle ....now the new cat is fine but the rattle is still there and i was told its down to a heat sheild now i havent a clue about under the bonnet stuff so i was wondering does anyone else have this or a similar problem or would anyone know what it might be? cheers lads
