Preignition catalytic converter

Has anyone installed a Preignition catalytic converter on their cars? Or any information about them.

We’ve had a number of threads on this. It’s a scam.

Do the folks selling this product have an address and phone number on their web site? Absence of these things is a clear indication that they can’t be trusted.

Thanks. I’m glad I asked before doing anything. I did sound too good to be true. I sent them an email 2 or 3 days ago but have yet to receive a reply. That’s when I decided to ask around.
