O2 Sensor Position?
Recently both of my catalytic converters broke and have begun rattling. I'm just wondering, can i replace the 2 main cats with high flow ones, rather than the stock mb ones, and if not, can i remove them all together without having the O2 sensor put the check engine light on?
any information on the subject will be greatly appreciated.

You need to have somewhere to put the downstream O2 sensors - they're the diagnostic sensors that check the cats and the other sensors are working properly. If you don't fit them somewhere, the engine will still run OK, but you'll almost certainly get an engine management warning.
