Hello all,

I’m looking to find a right side passenger exhaust manifold for my 66’ Olds 98. Very hard to find. Anyone has a clue where to get one or a reproduction?
anyone does headers for those? If so any contacts?

 

well if you can find em look for a pair of starfire exhaust manifolds these are dual exhaust,the drivers side has to go up and over the steering box,they are kinda rare and hard to find.but are out there.

 

If the '66 Dynamic 88 (425) is the same as the '66 Ninety Eight, I might have one . Do you by chance have the casting number ?

 

The RH exhaust manifold is the same on every single Olds full size built with a 425 or 455 from 1965-1970. The only difference is that the 1968-70 manifolds have the provision for the hot air stove - that version will bolt directly to an earlier car and work just fine. If you are looking for a brand new repro, no one makes them (the one Thorntons sells does not have the provision for the crossover for single exhaust). No one makes headers for these cars. The location of the steering box makes header fitment extremely difficult, and the minuscule market for such a product means that no vendor can justify the investment.

 

I have a pair off of a 68 98. PM if interested.
