Y-pipe for passenger side axle, auto to Manuel transmission swap

Post by Chadbartman »

Good evening all.
I finally pulled out my 1991 GW from storage for more 13 yrs, and finally swapped in a T18a / D20. I have not replaced the front axle yet to a passenger side drop, I am waiting on new leaf springs. So here is my question, what does the Y-pipe for a 1978 or older AMC 360 look like. I know I have to replace the one I have but can't find a picture of one anyplace but in the TSM. I need to see how it fits, so the front drive shaft will not hit the y-pipe.
Thanks for your help
Chad

In 1980 when the front axle drop was change to driver side, the driver side exhaust manifold and exhaust routing was changed. However, I do not think the passenger side was. It should still have the rear exit exhaust manifold and clear the axle and drive shaft ok.

Unless you have a lift, then you may need to rerout the driver side exhaust cross over. I had to do this on my '75 as the drive shaft wanted to pass through the exact area that the driver side cross over occupied.

Passenger side manifold does not change for 1980.

I can confirm, I have an 83 passenger side manifold on my 79. Clears everything great with a 3" lift.
