2nd Gen Non-Engine/Transmission four inch down pipe and muffler

[stumphumper]

I'm looking into putting 5in stack up in the bed of my 95 4wd ctd truck. I'm looking for a vendor/parts to change from my 3" down pipe, after the turbo, to a 4" then directly into a 4" muffler under the passenger seat area. I'm having a tough time finding just those two parts only and nothing else. I can rig it up aft of the muffler myself. Do you know where I can purchase these two items? Thank TDR'erssss.
