Technical From single to dual exhaust (oldsmobile)

Hello hambers
I have 2 98 oldsmobile 4door
1956 and 1953
They both are single exhaust
I thought to put dual exhaust on them with mufflers for a good loud sound
Can someone show pictures ?

 

On the 56, the exhaust runs from the drivers side around the front of the motor to a flow through on the passenger side manifold. You can either make a block off plate for the front half of the passenger side manifold, or find a second drivers side manifold to mount on the passenger side. In that case, you'll have to switch the head studs to bolts and fab up a new generator mount bracket that picks up off bolt mounting points.

 

Take it to a muffler shop and tell them what you want.

 

I would have thought the 56 98 should have factory twin exhausts? My 98 coupe certainly did and yes the front of the right side manifold had a blanking plate.

 

Not stock.

 

I thought the 98's were twin and the 88's single? I'm probably wrong though.

 

Im running fenton headers so they dump out in back of engine stock manifolds run to the front of engine

 

I have two 324's that were pulled out of 98's (a 54 and a 55). Both had the exhaust wrap around the front of the engine to the passenger side.
Possible that they changed to dual exhaust in 56 or later, but not sure.

 

My original’56 324 olds had a factory pipe going under the front of the oil pan
connecting the manifolds & exiting one manifold in one pipe.

Take Jimmy's advise and save yourself a lot of cussing, skinned knuckles and rust in your eyes! Take it to a known good muffler shop, tell them what you want, go to the local watering hole until its done.

 

Yes, but did it come out of a 98 or 88?
