2023 GR Corolla: The Horn Stinks…Luckily It’s An Easy Fix!!

Man, the stock horn in the GR Corolla is just sad....Luckily it is an easy project to replace the tiny stock unit with some big Hella Supertones and a few other supplies from Amazon.  Any idiot can do this upgrade in about 1 hour and with simple hand tools.  Enjoy!!
