Exhaust heat shields - optional?
A couple of the mounting holes on my heat shields have corroded through - the one under the boot floor and the one above the centre box in front of the rear sub-frame. Provided quite an unflattering tinny accompaniment to the V6's usually smooth progress, as you can imagine. Have temporarily fixed them back up with larger washers under the bolt heads but probably won't last too long. This can't be an unusual problem and I wonder how many cars are running around with the shields removed & if so, are there any ill-effects such as damage to paint/cables/pipes, heat soak into cabin?
