I have just notice a noise coming from one of the protection plates that sit over the cats on the exhaust. It appears to be rattling at idle, but goes away during hard acceleration. I don't remember anything hitting the underside of the car, so could it be a loose bolt?? :confused:

 

The quik-fit knumbskulls told me my cat was knackered and that I'd need a new one which was a main dealer part only and would be expensive. They were more than happy to obtain it for me and fit a new one for a small deposit of £100. Robbing phewkers!!! :xxx:

 

I've had it on the ramps but can see nothing obvious.....any clues???

 

Oh! it's a full stainless steel mongoose system.

 

Cheers

 

Bruiser :D

if the cats are done for then they do rattle, but usually it makes the car sound like hell while driving, my dads old merc had a fried cat and it sounded awful.

Had the same problem on my NA. The issue was that when the new exhaust was fitted they cut the heat sheild around the pipe. With an open end the filling between the heatshield and the exhaust fell out, causing the heatshield to rattle against the pipe at certain engine revs. Got some sealant from Halfords (one of them is good for silly temperature) pumped it inside the heatshiel, rattle gone.

 

I ended up, at a later point, just taking the heatshield away all together.:)
