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.
