As the title says, that is the car I have. The car is pretty much a survivor, meaning not restored, not modified that I can tell, but as things wore out they were replaced over the years. I am trying to replace the aftermarket parts that are not correct. The exhaust is a replacement system and I want to replace it with a correct system for the car. My 1972 Plymouth Service Manual does not have a diagram of the 440 for the B-Body but it does have a diagram for the 400. Are these the same? If not, if someone has a diagram I would appreciate it. The 400 diagram shows no X or H pipe and no resonators. Thanks!
