Have a question.

I have the HKS Downpipe, and the Blitz Nur-Spec exhaust. I still have the initial cat from my header down to the downpipe. Everyone seems to think I should not mess with this. Because if I do, I would then have not cat's at all. Probably would not pass Emissions. How restrictive is this Cat? Would I gain all that much if I knock out the honeycomb stuff that is in them?
As an alternate, would a Hi-Flow cat at the header do any good. HP wise, in place of this stock cat? I heard another 20+ HP?
