Mini Cat O2 Sensor adapter

Anybody try one of these mini- catalytic converter things in our trucks? Obviously these would not be for street legal trucks but could be a great way to keep everything running right without a Cat.

I've seen people use things like this with success but our o2 sensors mount with a 2 bolt flange not a threaded connection.

 

I didn't see any that would be an easy direct bolt on for our trucks but it wouldn't take much to modify things to make one fit.

 

Yeah you'd just have to chop and flange both ends of it
