I have an extra piece from my T-409 MBRP exhaust that I don't need. It is an 18 inch piece with a hanger. I guess it is the piece I would need if I had long bed instead of a short bed. If anyone wants it you can have it for shipping cost. Just PM me if you are interested in it.

You are right. That piece is for a LB. That piece used to be optional, now its included with the kits.
