Whistle tips became famous in 2003 through a KRON4 news report from Oakland, California about small metal inserts welded into mufflers that made cars whistle while driving. Interviewee Bubb Rubb demonstrated his car on camera with Lil Sis beside him, delivering enthusiastic lines that turned a local news segment into one of the earliest viral car memes. The clip spread through forums, file sharing and remix videos before modern social platforms, and its woo woo phrasing remains shorthand for over the top exhaust mods.
