Single to Dual Exhaust
I have a 1963 Dynamic 88 with FACTORY Single Exhaust converted to DUAL Exhaust.
It is like the newer years with the split out of the Right Side Manifold to Duals from there back. This conversion was available years ago and still is.
The Dealer I bought the Olds from had it done. It looks and sounds great and I still haven't disturbed the original Manifold set-up.
I did buy the LEFT Exhaust Manifold GM Group# 3.601 Part# 587793 in case I later decide to change to TRUE Duals. There are a few more parts needed to do the conversion:
A BLOCK OFF PLATE GM Group# 3.602 Part# 587576 for the Right Exhaust Manifold Cross-over Inlet from LEFT Side Manifold w/Gasket GM Group# 3.611 Part# 563689.
Left Side Manifold Heat Control Valve Assembly for DUAL Exh ( riser) GM Group# 3.640 Part# 588008.
Since any Muffler Shop can fabricate everything from the RS Exh Manifold back, this is an easier choice than the Parts Search. Since mine was done in Aluminized pipe, I'll leave it for now.
