delete the SECONDARY cats
New exhaust from the rear 02 sensors back
This is what most people do
That MRBP kit is nice!

To take it a step further would be to delete the PRIMARY cats (upstream, the ones closest to the engine, they should be in your Y pipe on a 2010) 
You do not need stainless steel cat converters to get an all stainless steel system would require stainless headers, stainless downpipe, and stainless cat back awesome but not really needed. :)
