It not to difficult just having the right tools helps out alot. a torch is good but you can also use a reciproicating saw it creates a much cleaner more workable cut and then get some adapters and u clamps for reinstallation. they also make a exhaust sealer almost like caux type stuff that would be a good idea to put that around the adapters.

This is a job you can't do at home without a torch to heat the exhaust pipe, the converter is a slip fit and nearly imposable to remove without a torch, on the ground it will require 2 people in most cases to get it off, one heating the pipe read hot and the other pulling for all it's worth.

How do you know if your cat converter is going bad? Can you test for it?


There are two ways a converter can fail:
  • It can become clogged.
  • It can become poisoned.
There really is no "inspection port" for the consumer or mechanic to see an actual clog in a converter. Often, the only way to tell if a catalytic converter is malfunctioning (plugged) is to remove it and check the change in engine performance. When a clogged converter is suspected, some mechanics temporarily remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance.
A catalytic converter relies on receiving the proper mix of exhaust gases at the proper temperature. Any additives or malfunctions that cause the mixture or the temperature of the exhaust gases to change reduce the effectiveness and life of the catalytic converter. Leaded gasoline and the over-use of certain fuel additives can shorten the life of a catalytic converter.
A catalytic converter can also fail because of:
  • Bad exhaust valves on the engine
  • Fouled plugs causing unburned fuel to overheat the converter
­Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter. A partially clogged converter often acts like an engine governor, limiting the actual RPMs to a fast idle. A totally clogged converter causes the engine to quit after a few minutes because of all the increased exhaust back pressure.
The catalytic converter, like the rest of the emissions system, typically has a warranty length that exceeds the term of the warranty for the rest of a typical U.S. automobile.
Here is a safety reminder: Do not park your car over tall grass or piles of dry leaves. Your car's perfectly running catalytic converter gets very hot -- enough to start fires! You can keep it running well by keeping the ignition system in top shape, to prevent any unburnt fuel from entering the catalytic converter.

Where in the engine is the catalytic converter


The catalytic converter is part of the exhaust system and is usually found under the vehicle, and the exhaust will run from the exhaust manifold to a pre-catalytic converter, and then down to the catalytic converter, and then the exhaust will run from the catalytic converter to the exhaust muffler, and then continue out to the end of the tail pipe.
I have provided an image of the catalytic converter to help assist you.

Replace muffler, not the catalytic converter which started to rattle. Stop running, will crank but will not start. can it be the catalytic converter.


if the converter is rattlin then it needs to be replaced because the element inside is broken. if the jeep still does not run try removing the catalytic converter to see if the restriction is too much. should start if the converter is restricted. if it doesnt maybe its whatever caused the converter to go bad in the first place
