Burn Smell from the engine

Hi Guys,
When i drive my S320 around for like 20 minutes and this happens if i usually drive fast, i get a burn smell frm the engine compartment. It like some kind of wire or copper is burning. Would you know what that might be?

Thanks!

Oil is changed with Mobil1 Full Synthetic Oil every 3000 miles. Gas is always 93 grade.

your catalytic converter is going bad, that smell is sulfur dioxide (which smells like rotten eggs).

check under car to make sure no insulation has gotten loose and is touching the exhaust system. alot of times on older cars the heat insulation under the car gets loose and touches exhaust system somewhere and can start to melt/burn.
