HiFlo Cats or Cat delete?

I have stock headers and stock cats now that go to a xpipe and borla stingers and I will be installing long tube headers and either hiflo cats or just deleting the cats alltogether. How much of a horsepower difference will i see if I do a cat delete over hiflo cats? I also live in florida so i dont have to worry about emissions

I have heard stock to high flow 3-5 and none 5-7. I think more is to be had with a good tune.

Someone hear did a before and after dyno with and without hiflow cats. I think he lost about 3hp with.

Not running cats will make your exhaust stink really bad. I ran my car for a week without the cats... I Will never run without them again.
