Who makes the best Hi-Flow cats for a 4.6L

I am wanting to get some hi-flow cats for my 05 4.6L and was wondering who makes the best hi-flows for our trucks? So far I have installed a S&B cold air intake and a Magnaflow 14" si/do exiting in front or passenger rear tire. I have noticed a slight increase in power. If I was to get some hi-flows, what gains would I see? Thanks for the help

You wouldn't see/feel anything besides your wallet empty.
