HFC's do have a chance of passing the sniffer..so ive heard. also, as long as they arent SUPER SHINY POLISHED CHROME/STAINLESS STEEL, it might pass visual as well. most tech's dont know the difference between a stock cat and an aftermarket one after the steel has changed colors and darkened.
you could always chance it. most places will retest if you fail for free as well...
