You know, I've not priced TP's, but compared to HFC's, that's a heck of a good price. Catalyst material must be pretty expensive. I wonder if a corner shop would look at that resonator and think those were cats? At only $160, I think I would have taken a shot with these and see if I could get by here in NY. Inspections are serious, but they're also just visual.
