Was wondering if anybody has a diagram on the factory exhaust system for a 64 Ninety Eight sedan? Cant seem to find any diagrams on the web. Wanting to do dual exhaust on my 64 without going on the hunt for a different exhaust manifold just to run duals. Thanks

There's a reason why the manifold is different for duals. You won't be able to do without it.

Here's a diagram of a 1963 full size Olds . '64 is essentially the same .
While some muffler guy could probably cobble up a pipe , the space constraints are very tight , and the pipe would hang down below the rest of the bottom of the car .
Also the pipe would be very close to the starter , and cause that to be "cooked". Joe is right , there is no good way to do it .

What's wrong with single exhaust ? The single exhaust system is more than adequate for the stock engine .
The 98 is no Hot Rod anyway .

That dual exhaust manifold comes up for sale from time to time.

I as well have 64 Olds 98 2 Dr holiday coupe making it mean and want duel on mine but put a flowmastersuper 10 and sounds great but duel will give it more agressave sound as it's not a Ford pickup it's a 394.ci. and it's fast and not alot around...
