How to replace/remove both catalytic converters

Have to change out both catalytic converters in my 1999 2.7 l Dodge Intrepid to pass state inspection. Replacement direct fit parts have arrived. Are there any tricks to this? Do I have to drop the entire exhast system to replace the catalytic converters. The converters are up front/first segments of pipe. How do I get enough clearance to remove them with out dropping the entire exhast system?

Below are the steps needed to remove the catalytic converters. You may be able to first remove the band clamp from between the converter and the exhaust manifold, then loosen the rest of the system and to get enough clearance to slide the converter towards the front of the vehicle but you will need to first remove the clamp that holds the converter to the rest of the exhaust. Hope this helps
Both Catalytic Convertors

First you need to raise the vehicle.

Next, you need to pry the insulators from the support brackets and support the muffler and tailpipe with jackstands.

Then, loosen the the catalytic converter down pipe-to-front resonator clamps and separate the front resonator from the converter down-pipes. Carefully lay the free laying exhaust on the ground.

Right Catalytic Converter

Then, remove the down-pipe-to-transaxle bracket nut, loosen the clamp and separate the extension pipe from the converter.

Next lower the vehicle and remove the air filter and intake ducts. Disconnect the wiring harness for the O2 sensor and the remove the sensor.

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment. You may need to replace these clamps after removal because you need to pry it apart and they will leak when you reinstall.

Left Catalytic Converter

Now disconnect the wiring harness for the O2 sensor and the remove the sensor.

Next remove the down-pipe-to-transaxle bracket nut

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment.

Engine shakes

Could be 8 different things

Could very well be a worn out converter
They last 12 to 14 years,after that you can
replace even if it still passes inspection, it isn't
doing anything,but not the shaking issue

Timing chains/belts,spark plugs,vacuum leaks,egr,

Mechanical Valve Wear,loss of compression

There are two type of emission classes.

Federal and California emissions.

Look under the hood for the emission class sticker.
Smog check station's machine in CA are programmed to handle both types.

You do not need to change anything before the inspection.

How do i remove catalytic converter from dodge intrepid?

Usually if they are bolted on the bolts are so rusty they will just break off. I use a sawzall to make a cut in front and back of the cat. Then the easiest way is to use clamps to install the new one.

Will no pass smog test

Your catalytic converter may be shot but first I would replace my upstream and down stream o2 senors one at a time first to see if it will pass. Hope this helps!

Catalytic converter

The short answer is NO... It's not like changing a muffler in the "good old days". They are welded in and need to be cut out then rewelded, etc... not an easy job unless you have access to shop tools.
Can I ask WHY you need to change the converter??? They usually last as long as the car. I recntly sold a 1998 Olds with 245,000 miles on it and it had the original converter intact.
Good Luck
