Parting together a custom exhaust setup - Questions

Hey guys, my H&S XRT Pro just arrived. I would like to install it, but i want to finish parting together my exhaust setup. Im a bargain hunter, and i sourced a brand new 4" 2 piece flo pro downpipe for 65 bucks. Now i want to complete my setup with a 5" down pipe back setup. Im having trouble getting information. At what point would it step up from 4" to 5"? Im also having trouble finding a coupler of some kind to step up to 5". I know i could have bought a complete kit, but like i said i look for deals. I have less than 500 invested in the XRT tuner and downpipe combined. If anyone has some info, i would greatly appreciate it!

I forgot to mention that the downpipe has a 4" ball/socket flange on the exhaust side. I guess i would need that 4 to 5" coupler at that point?

5" exhaust kits step up from 4" after the transmission crossmember.

Ok great, thanks for that info! So it would probably be best to come off the downpipe with a 4" pipe, then step up to the 5"
