Default H-pipe no cat exhaust?

I have a 96 WS6 TA with the LT1 and have already purchased an h-pipe with two 3"x16" Dynomax mufflers. I was told to put the system on with out cats, but im wondering if that would screw anytrhing up (downstream 02 sensor wise) . Also, if i got long tube headers, would it be better to keep the egr fittings or remove them?

If you don't have to deal with emissions, get rid of all that junk. EGR is just a pain in the ***, that garbage is always in the way.
