318 Engine Y-pipe

["Don Hudson" <mopar4me@xxxxxxxxxxx>]

Didn't they also use the mini cats on Miradas?  I had one a few years back and it had them.  My 81 Imperial also has them and they have to be restrictive.  I will probably convert the exhaust to a quiet dual exhaust with dual cats.

The Y-pipes are totally different, - guess they did that so we could not
"trash" those mini-converters easily.

Hmm, I'm surprised at that. Do you know what the exact difference is, and how it effects fit? I don't see why the exhaust system from any F/M/J shouldn't fit an 81-83 Imperial. If your car is no longer injected, and you wish to improve the abysmal exhaust system, you might consider exhaust manifolds from the Magnum series (92-03) of Chrysler small-blocks. Much better flow without the drawbacks of headers. However, I'm not sure if any of these truck applications will fit F/M/J's. Might be a good tech question for the Mopar Action website, I'm sure I'm not the first person to think of this.

For those who don't know...

F= Aspen/Volare (all)

M= Diplomat (78-89) Gran Fury (82-89) LeBaron (78-81) 5th Avenue (82-89)

J= Cordoba/Mirada (80-83) Imperial (81-83)
