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

it's a heat shield.
you can remove it but be aware of why it was there in the first place.

thank you

clear now that better leave it on
sorted 😂


added square furniture (?) spacers with 2 holes instead of original spacers under 2 remaining bolts, connected them with zip cable ties

front secured 😂

rear one: found a 2 holes on the center side closest to the shield at around the middle of the heat shields length

zip ties through

connected several zip ties together, wrapped around with aluminium foil, got it on top of exhaust (extra layers of aliuminium foil on zip ties just above the exhaust), connected zip tie chain to the front zip tie between 2 bolts

turned the engine on - no more noise.

might last for a while, i need fix it properly.

final question: is the heatshield aliuminium?

Probably some cheap alloy, try it with a magnet and see.

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

They are aluminium. You can get 'rolls' or sheets of it to cut and fit yourself or you can get replacements from Honda if you'd like to retain them. Otherwise, take them off. I've done several track days without them. Just don't go for a spirited drive with any perishables or frozen goods in the boot and you'll be fine!
