Default High flows??

Who's high flow cats do you gus recommend? I do need cats for emissions but not the standard cats. I have longtubes with a 3"ory from tsp. I know i will have to modify my Y-pipe but that is ok. So suggestions on fairly price high flows would be great. thanks!

I engine dyno tested Dynatechs high flow cats vs. no cats at all. On a 500hp 6.0L, there was a 4hp difference. You wouldnt ever feel the difference.
