I had exhaust like rattle every time start stop engine, quite loud, i heard nothing when driving, mild rattling at idle. Checked today, it appeared to be "foil" thats above the exhaust

holes bigger than washers...

anyway, managed to "secure" front from touching exhaust, but rear bolt just broke whilst undoing, and cant find a way to attach the rear of that foil.

Do I need that "foil"? Why is it there? Can I rip that foil off completely?

Thank you

I'd be more concerned with rubbing down and treating your surface rust before it gets any worse.

I took off my heat shields when they started rattling. I didn't find it got particularly hot under there. The cat is in the engine bay so most of the heat is around there rather than under the car. Don't know if it's any different on the 2.2 or FN2, mines a 1.8
