original exhaust

[curt1992mj]

hey dose anyone know if the original exhaust on an Comanche has a catalytic converter? when i bought my jeep it didn't have one and i recently moved to a place where you need a cat if it originally come with one. and i don't like them i never had a cat in my life, and i don't want to have to modify my exhaust again.

All MJs originally came with catalytic converters. AMC started putting them on the original 84 XJs.

I honestly don't know. I bought mine with no cat and looks to be factory or a really good exhaust job
wish I could be more help but figured I would add my input

Out of 12-13 MJ's Ive been thru, only a couple had CATS.

As Hornbrod has posted, ALL Comanches (and Cherokees) had catalytic converters when they shipped from the factory.

Federal mandate since 1984. all Comanche's had catalytic converter from factory. Look under hood there is sticker. I have a pass thru in my converter because after 25 years in Texas the cat has to look like it is there but no emissions testing.

Actually the EPA mandate came out in 1975. AMC started installing cats on their gasoline vehicles in 1977.

Yep. They all had them from the factory.

You should have a rectangular flange by the trans cross member. This is where the cat mounted before going into the muffler. If your pipes are in good shape just buy a universal cat or universal high flow cat and have it welded in. No big deal really.

Catalytic converters have been installed on most 1975. however The policy August 5, 1986 was when it was enforced.
