Most complete Single Stack Kit? Vendors?

[flicker]

Decided that I want to go with a single 7" mitre cut (black) stack on the truck, problem is I just moved and won't have a chance to move my toolboxes/welders for a couple months, so I need the most complete turbo back kit (yes, I need a new downpipe) that I can get to keep fab work down to a minimum. Hopefully a site vendor can help me out with this, if not give me some ideas. 1997 crew cab short bed.
