Catalytic converters

Hey everyone, I'm mainly an FBBO user, a coworker told me about these that were patented in 2020. I think he did not like the ride in my 70 RR. :) I just started poking around and found this thread to see if anyone had been brave enough to try them out. Very interesting and there is a demo of an old british car with these Classic Car Converters. Curious mainly but I wanted to pass it along to the thread starter. Who knows if they'd work after a few minutes on the highway.
