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.

Interesting. I have seen some people ask about catalytic converters for getting rid of the “old car smell” that comes from the unburned hydrocarbons etc. you get with the older carbureted engines. Personally I like the smell, but of course it’s carcinogenic too. And people that have a 2-story with a bedroom over garage layout might not appreciate it as much either.

The issue is that on carbureted engines the catalytic converter’s tend to foul pretty quickly, they don’t deal with the extra fuel in the exhaust or lower exhaust temperatures as well. It would obviously be different on a classic that had a modern engine swapped in, although depending on your modifications you could just use the converters that would be right for that engine. And running EFI would also solve that issue, although again that would also open up more converter options too.
