Exhaust: from shorty header to where long tube collector would be.

[dhunt00c]

Hi all. I have a 68 chevy C10 and bought Hedman mid-length ceramic headers. Also bought a Flowmaster 2.5" stainless exhaust kit, but I don't really have any pieces/bends that allow me to run the exhaust directly from the shorty headers collector down to a point that i can just do the regular runs onward to mufflers and back of truck. So basically some piping and bends to match the rest of the system (basic stainless from Flowmaster) that would run between the end of the short to near where a long tube header collector is. Any recommendations on what intermediate pipes/bends I need or can get to run this portion of exhaust? I can post part numbers if that helps. Thanks in advance!
