The Subaru Impreza WRX STI is a high-performance version of Subaru's Impreza, long associated with rallying and Japanese tuning culture through its turbocharged flat-four EJ20 engine and distinctive exhaust note. Short clips of that engine sound have circulated widely on soundboards and in car videos, where creators use them to evoke speed and motorsport without needing footage of a real car. The STI badge itself has become shorthand for aggressive, rally-bred performance, which keeps this particular rumble instantly recognisable to car fans online.
