Not to offend anyone here but the idea of injecting fuel directly into a catalytic converter to me is disgusting. I like this much better. The reason I use the term disgusting dates back 40 years to the first emission controls and the continuous additions of many "bandaids" to the problem instead of "fixing" the problem itself.
Please do not think of this post as any kind of flame, it is not intended to be that. I just want to see the core issues addressed, instead of squirting fuel into a catalyst.
Make the combustion cleaner and eliminate the catalyst altogether. Then you don't have to worry about some thief with a battery powered chop saw stealing the platinum out of your car!

I think this system holds a lot of promise, but I haven't bought any of their stock.
Yet.
