is the system and components the same for 65 and 67
I have a complete original 67 set removed from car early on, from headers back.
would the y pipe, muffler, resonator be the same?
both are 273 commando cars. thank you
 
There was no "HP" exhaust for the 273.
 
No, the 64-65 273 had a rear facing driver side flange, the later (maybe even 66?) had a downward facing flange. Check out the clearance divot between 3 and 5 ports on the 65 for the power steering box!

My apologies then. I don't know why the heck I read manifolds into it. He clearly said exhaust components. I took a stupid pill I guess.

I do that all the time. Often when doing moderator duties.

You should be able to make it work. Might take some work on the left side head pipe or using the later manifold. Whether it is exactly the same? I doubt it, but...
 
65 engine bays can only use 1964-66 273 manifolds, putting 67 273 manifold on an early a will not work, on the driverside because of the manifold outlet being different, but on the passenger side it is the same.

A-Body HiPo Exhaust System

67 is listed separate but it looks like it's because the manifolds are different as mentioned above. I don't see different pipes listed for 67 though. @lkopaska has a new system on his 67 he is doing. I bet he would know.

thank you, yes, I have the manifolds. I was wondering if the y-pipe, the longer pipe, muffler and resonator were the same.
I should have been more specific, but wanted to know if the factory power pk exhaust from a 67 Commando car would fit on the 65 commando car.
Thank you all for the quick responses. much appreciated!
 
I don't know if the hanger locations would be the same in the rear, either. Look at the long rear overhang on a 67 compared to a 64-66. I'm sure an exhaust shop could make it fit, one way or another, but the y-pipe is different, as already established, and I doubt it would be a straight bolt-in anywhere. But you have the important component -- the resonator.
 
Just find a good muffler shop they can make it work, they can use what you got and add what you need.
