kooks headers?
ARH will also do this or free if you just ask I ha them do it for me.
It's not so much that the 1-3/4 stepped to 1-7/8 offer the flow of the larger primaries but the smaller diameter primary first helps with velocity and pulls the exhaust out of the head. There have been instances where they have been proven to make more power than 1-7/8 but I haven't seen any done on an fbody and also they are much more$$

I'd buy the Kooks Headers and y-pipe just because you can upgrade to the true duals later. Yes, I wish the y-pipe had a better merge and a cutout provision standard, but it'll do until you need to start looking at the duals (450+ hp).
mine are not coated though it looks much better imo.
