Purple Hornies exhaust
Friend of mine at Miramar got a ticket, put these on his 55 Chivvy with brand new headers around 71-73. Came back to the hobbyshop, laughed, shook his head. Said the "CHP at the inspection station wouldn't even let him in the office." He dug around in the dumpster, dug out FOUR old glass packs people threw in, welded 'em all under there, and went and got passed. Then came back, threw it all away and put those awful awfuls back on.

Most irritating, obnoxious, and obviously illegal "so called mufflers" ever made.
Haven't heard that name in years and years.
