Ok thanks so far but I still haven't got the answer.
Can anyone identify, on that image, the front exhaust heat shields?
I have also been given this answer but again it doesn't narrow it down:
" Exhaust heat shields are designed to protect areas of the vehicles floor
panel and adjacent components from excess heat generated by the exhaust
system.
In regard to the question from Murray, they can be located anywhere from the
exhaust manifold to the centre exhaust silencers which include area 'B' in
the diagram."
