I’ve got something going on. Sounds like it’s coming from the passenger side floorboard which is where a large heat shield it. The heat shield most sounds fine, but it had been bent to install downpipes so it’s potentially compromised?

Mine was the IWE , vacuum line got cut when replacing shocks.

Anyone fixed a rattling sound from the passenger side. When I give it gas sometimes it rattles. Sounds like thin metal rattling like a heat shield but i cant seem to find a heat shield anywhere.

I have the same issue on my 2014. My mechanic and local Ford dealer concurred that both catalytic converters were bad. I replaced them yesterday and eliminated all clamp fittings with welded joints. No joy as the intermittent noise continues when acceleratin. Again, it’s intermittent and sounds like the passenger side. I’ve checked every bolt, under the hood and under the truck. STUNNED!!
