exhaust for large displacement?
Mine are the 1 7/8 stepped to 2 inch and i don't think i'm leaving anything on the table here so just looking at lightening the exhaust up a tad. I wonder what the weight of the whole off road system is?

I think you will be ok running the 1 7/8 stepped headers. Vengeance Racing did a 440 a while back using 1 7/8 headers using tfs 235 heads and slp Dual dual catback... Car made 582rwhp and 534lbft. I would think you shooting for 600rwhp tho and I think the 2 inch headers would get you closer to that mark.
Like LPE403 said, it is really no different than a 1 7/8" header.
I put mine in from under the car and had no issues, did it alone too. My car was up on 12" wheel cribs.
Good luck with it.

Verdad Gallardo im thinking about going with the stepped from 7/8 to 2". im thinking it might help with clearance, plus scavenging. the 3 1/2 collector worries me tho since im lowered
I would go with the stepped 1 7/8-2" headers if I were you. Like you said better scavenging and should pick up a little more tq than a full 2" primary. I've got ARH 1 7/8" non-stepped on mine.
