I don't, but from what I've seen I think catless w/ stock 2nd cats is the hot ticket. For those that don't want to run simms, you could also relocate your 2nd o2 sensors behind the 2nd cats.

And add about 5 feet of cable.

I am really curious how those South African units work out. Pretty interesting that they have cat material in the extender.

Yeah that does sound pretty neat! If people want to go that route do it before you install the downpipes. Getting to the sensors after the fact is a bit of a pita.
