The 1965 Oldsmobile F-85 originally was outfitted with a pretty interesting exhaust system. The original cars had a 2″ head pipe on the left hand side and a 2 1/4″ head pipe on the right.  The small block Oldsmobile had a unique attribute from the factory.  The passenger side manifold used a cap to cover the one outlet of the manifold allowing the cross over pipe to be dropped and turn the motor into a duel exhaust application.  Our reproduction kits can include this cap flange as well as the  correct mufflers, installation instructions, diagrams, sealant, clamps and correct front and rear hangers.  We have chosen to provide our kits with 2 1/4″ head pipe on the driver side so everything looks symmetrical.  Ask about our concourse show package for those of us when original is not good enough.

Ask about our turbo mufflers for a little extra roar!
