For the bolts on the headers, ARP LS1 bolts is what I used.
You'll need a tune. It's going to run like *** until you get it tuned.
The muffler may be OK where it is but mine is closer to the axle.

I spent some time looking yesterday and did find the dual set up on the Kooks (and Summit) website. It appears to be a 2006 Silverado SS 6.0 set-up (as mentioned by Snake-Oiler). I don't have a lot of knowledge of the different models of silverado i.e. SS with 6.0... but I am learning... Anyway it is Kooks part no. 28523200 3" catted connection pipe for use with kooks headers. As far as I can tell, the intermediate pipe will work in a rcsb of the same era and possibly later models as other non-SS y-pipes etc. look to be the same part no's between the two generations (mine is a 2010 rcsb 2 wheel drive with a 4.8).
Magnaflow offers a complementing SS 6.0 "intermediate pipe to exit" exhaust system part no 15840 includes, resonators, and magnaflow dual in dual out muffler but it looks like this is for a extended cab models only (apparently SS's are only extended cabs?). I prefer both pipes exit out the passenger side behind the tire anyway, so I will keep looking for this set-up or will have to get a custom set-up at a local exhaust shop. I won't likely be doing this until the spring or summer 2016, so I have time to search and learn...
