87 V10 Factory Exhaust

[WP77]

I'm looking for the factory muffler and dual left side exit pipes for an 87 V10 long bed. Mine still has the dual exit muffler, but a previous owner hacked off the exit pipes underneath the pickup. I checked the Walker catalog and they want to sell a single exit muffler and single pipe. Does anyone know where I can find a factory setup?

Iirc, the Walker book used to list the dual tailpipe setup. Maybe find a shop with a really old book and search for the old part numbers on eBay and such? Or find an exhaust shop that does custom bending and can mimmick the original setup?
