Code Q Dual Exhaust for 1974 Gran Torino

Unfortunately, I believe that the Q codes in 1974 had a single exhaust, unless I am mistaken. I have a '74 CJ engine sitting in my garage with the original manifolds, and a '72 original CJ exhaust system. Looks like they would interchange, but not sure.

ALL Q codes were dual exhaust.  i do have a pair of 4v manifolds that are correct for your car.  the passenger side had two cracks which i had repaired.  they do need new studs.

Sanderson shorty headers are an option, not sure which set is needed for a Torino?

pretty sure they will mix/match the left & rights to make a custom set

Thanks for your proposal. But repaired cracked cast iron seems fragile to my eyes. Maybe I could go for that, temporary...
Could you please send me the part numbers of your manifolds?
Anyway, all your replies are more confusing to me. Opinions are so different. I would be happy to see a picture of an original Torino 351 CJ exhaust.
I'm pretty sure it was a dual.

I will get casting numbers when I get home tonight.  As far as differences, here is what there is.

Well, those informations are very useful.

yes, stock pipe diameter is 2.25"

68-72 A-body (chevelle/cutlass/lemans/GTO/Skylark)

the connection to the factory manifolds would obviously be different from a Ford to a GM, but the basic system after the down-pipe can be used. this link is for 'header back' options, to remove that just click on the X to remove on the left side, or you can select other options down the row

HEre are the casting numbers the seller just sends me:

DOAE 9431 O

DOAE 9430 G

Are they correct?

Thanks for the replies.

Here is a picture of the DOAE 9431 G and DOAE 9430 G exhaust manifolds.

Your welcome, The DOAE 9430 G right side (passenger side) exhaust manifold, will fit your engine inside your 1974 torino.  The DOAE 9431 G left side (driver side) exhaust manifold will fit onto your engine perfectly, but I have just learned that the DOAE 9431 G left side (driver side) exhaust manifold will not fit into your torino, because it will touch the power steering box/gear. But i have never seen a DOAE 9431 O exhaust manifold, maybe it will be different? You will have to find the correct part number for the drivers side exhaust manifold that will fit your 1974 torino. Here is a link of a person who had this same problem with the drivers side exhaust manifold.

You can find the DOAE-9430-G passenger side exhaust manifold and the D1ZE-9431-BA drivers side exhaust manifold (with the 2 inch exhaust port) from any:
