I think a fair amount is pumped in. Ford loves fake engine noise. To be fair, they kinda had to do it with those vagisil powered motors in the 2nd and 3rd gens. Even still it’s an awful sound. Like a Dustbuster getting ***** by a weed whacker.Yeah out of all my sports cars the raptor r has the second best sounding exhaust. I like the burbles and pops. My 2023 Urus has the best exhaust however and its exhaust (and looks) turns heads while driving. The raptor even in Baja does not so I wonder how much is pumped into the cabin?
