Do I have to have a catalytic convertor on a 1984 Cherokee with 2.5 liter? From what I understand, by law you have to (Missouri). If you run one without, will the Jeep still run? Will it cause any problems (long term and short term)?

 

Run with one coz its the law. Read converter thread. Sticky on this section. 4th thread from the top.

 

Ok, I will, as these emission things are getting more attention, no need to ask for trouble.

 

You can run without one without a mechanical problem.

 

As someone said. U won't have any probs since its carborated but its the emission laws that u will be dealing with in the long term. There r a bunch of carb legal high flow cats available now that r close to the price of regular oem replacements.

 

seriously i don't know why everyone makes a big deal out of cats. It's like $100 for a good high-flow magnaflow cat, and your jeep won't smell like **** when driving

It's federal law, like it or not.

 

Is why older vehicle small like oil/gas when they pass? I am sure they have no emissions and not properly tuned.

 

i high flow spun cat on ebays is $40 shipped... there almost the same size as the exhaust pipe itself... so no worrys about catching it offroad... and no 90* bends in it... all smooth and slick... there what i always run... not only is it federal law so it excludes any state law out there... its also a must have by 95% of offroad clubs out there... so dont think youll do much REAL trail riding without one...
