Just wondering...I have a 57 special with the single exit exhaust. I want
to upgrade to true duals. Would i have to get special downpipes or can
I just remove the factory crossover pipe and run from there? Also noticed
that it seems that alot of restorations have exhaust finishers going through the factory deflectors in the rear bumper ends. Would I be able
to use the factory deflectors or are finishers recommended??(an old timer
told me that the factory exhaust exit causes bluing of the rear...
