It should only have one. It has a single exhaust and a small engine, no need for more. Your 2 pipes cross over into one and then go through the catalytic converter then on to the muffler. Hope this helps.

How to clean catalytic converter


No, the oxygen sensors are not in the converter itself, but upstream in the exhaust, and sometimes one on the rear of converter in the exhaust, but not in the converter.
There is no additive that can do anything for the converter. A well-maintained clean running engine kept in good tune is your only insurance against a plugged or failed converter.

Tip

RECYCLE THAT OLD CATALYTIC CONVERTER


Sooner or later, most cars will need to have one or more catalytic converters replaced. The old converter off your car or truck can be recycled for cash. Some of the older converters are worth enough to pay for having a new one installed. But most people are not aware of how valuable they are, so they let the muffler shop or repair shop keep the old converter. The muffler shop will recycle the old converters for money that should have gone in your pocket. Personally, I think there should be a law that requires the muffler shops to give the old converters to the customer, or have the customer sign a waiver saying they do not wish to keep the old converter. The waiver should state that the converter can be recycled for cash. And if they waive their right to keep the old converter, the muffler shop should be required to reduce the cost of the new replacement converter by a percentage of the value of the old converter.

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.

Its cutting off going down the road and taking 20 mins to 2 hours to crank temperture light flickers before it dies. I notice the manifold glow red hot Thanks Keith


Keith if manifold is red hot that tells me it is running very lean it is either got a plunged fuel filter /bad 02 censor or plunged cadlitic converter/possible bad temp censor you real need to start by reading the coeds /and/or have the car scanned /you can read your own coeds by grounding the ALDL connector if you know what that is if not you can take it to Auto Zone they read coeds for free then once you have the coed return hear with them and i or some one else will help you work through them to see the least expensive way to git it fixed.

Hi, I had a hitch installed on my tucson 4 years ago at uhall.tried hooking up trailer yesterday for the first time but all lights wont work.park lights find.signal lights and break lights won,t work.if i...


yes it sounds like the converter is no good,the converters purpose is, when you have a trailer it uses the brake and signal on the same bulb, so if you were to step on the brake and have the left signal on, then the left brake light would turn into the signal,on your truck it has sperate lights for signal and brake, the converter converts this into one light for the trailer, so just replace the converter and everything should work fine, hope this helps.

get a can of liquid freeze at an an electronics supplies place.it is made by mg chemicals.
you spray defective components and the -60F spray cools down the part and the problem goes away.
it does create moisture,so be careful with HV circuits,but it is amazing for finding modules that cut out when hot.
i have used it for years in electronics to find bad diodes and transistors and ic s .
