Has anyone installed the euro (or aftermarket header) but gone to an aftermarket cat setup to help with the placement of the O2 sensors??

I guess what's going through my mind is I have the euro header, but I'm not too crazy about cutting up the secondary cats portion. The euro cats are crazy expensive. Wondering if going to a custom setup for the cats would be more cost effective as well as helping out with the wiring due to placement of the sensor bungs.

Thoughts?
