Exhaust burning smell while flooring it

[chipmunk62]

Anyone else have this happen? My 2021 Aviator starts smelling like exhaust or something burning inside right after i floor it and then let off around 100-120 mph. I'm not gentle with it at all, I drive it like its my last day on earth, so I don't think its just the cats getting loaded up. Wondering if anyone else has dealt with this?

Oh this happened to a friend! he mentioned that hard driving at high speeds can cause those smells, especially if there's a minor exhaust leak or heat shielding issue. Try checking checking the seals near the firewall or turbo connections.

Heat soak or something is cooking off, and I'm just hearing about this speed thing for the first time, well..check for any small leaks near the downpipe or turbo gaskets, and make sure the heat shields are all still good
