Adding high flow cats to catless setup

Hey Folks!

I did some searches, and saw a few passing comments, but no real intel here.

Has anyone bought catless downpipes, then got a set of high flow cats and had them added to the midpipe?

The cost of downpipe with high flow cats, that I've see, are just nuts. I want a more edgy sound, but am not ready to sniff my own exhaust fumes sitting at the stop light.
