Current Mods: SSW long tubes and 2.5 inch high flow cats merged into 3.5" single exhaust...intake...ported throttle body....efans...tune.

Planned mods in the next few months: Heads and cam

My question is I am wanting to do true duals, and I am thinking about doing 3 inches from the headers back to the cats then 2.5 inches from the mufflers back. I have got to purchase pipe for the exhaust either way, just trying to decide if going 3 inch cats for the extra flow is worth it? And what brand cats would yall go with? I think the cats SSW sent me are random technologies if memory serves me correct.

I am not looking to get rid of the cats, just want plenty of flow for my future mods.
