If it came from the factory with a cat it is aganst federal law to remove it... also if it has o2 sensors before and after the cat it will affect running of the truck...
Catback is shortened slang for "everything back from the catalytic converter". It is a bolt on exhaust which connects to the rear of the pipe holding the catalytic converter, and ends with the muffler and exhaust tip. In short, you need a cat to have a catback.
As long as the muffler and catalytic converter are intact
the cat is a short term for the catalytic converter. An exhaust system component. It helps to keep pollutants down.
P0420 usually points to a failed catalytic converter, if the exhaust system is intact, that is. Exhaust leaks in front of a catalytic converter can affect the O2 readings and at times throw a false code. P0141 indicates only the heater circuit of the o2 sensor has a problem. Usually it's the element in the sensor, and replacing the sensor would fix that, but it doesn't rule out a harness issue or a short in the wiring
A catalytic converter overheats due to an excess of unburned hydrocarbons reaching it through the exhaust stream for an extended period of time. This overworks the catalyst bed inside the converter, which then starts to become plugged, generating even more heat as it does. In short order, the converter will become a significant exhaust obstruction, causing the engine to overheat and lose power. Eventually, this will prevent the engine from running, due to the inability of the exhaust to escape, denying the engine the opportunity to "breathe"...
The catalytic converter usually has an Oxygen Sensor before and after the converter. The hot exhaust gases of the exhaust heat up a catalystic and the voltage is proportional to Oxygen. By measuring before and after the catalytic converter, you have a sense if the Catalytic converter is working correctly in cleaning up the exhaust. The exhast to be cleaned up correctly requires the PCM to sometimes run Lean fuel mixture, to clean up NOx, and sometimes Rich mixture to clean up HC (Hydrocarbons). So PCM cycles the fuel mixture between rich and lean many times in the process of driving, so that to get optimal efficiency of the catalytic converter. However, if you have a vacuum leak, your engine will run LEAN and the PCM will compensate and force it to run rich instead. After a while, by running rich too much, you are throwing unburned fuel into the exhaust pipe, causing Catalytic converter to become Red hot and causing it to fail. So in short, running Rich, not lean, can cause converter failure.
If you mean drain your gas from the tank then no. The catalytic converter (catcon for short) is part of the exhaust system which only deals with the burnt gas coming out of the engine. If you mean drain your gas mileage, then yes. When part of the exhaust is clogged up the engine has to work harder to push the gasses out which means it'll burn more fuel to create the higher pressure required to push the exhaust past the obstruction.
A misfire on a car with a catalytic converter will overheat and destroy the converter due to unburned fuel in the exhaust. on a car without a catalytic converter, it will still wash the cylinder with unburned fuel and break down the oil, but not do any serious damage in the short term. it is possible but not good because u can screw the rest of ur motor up it is better to fix before u drive it
Front wheel drive vehicle engines move when you accelerate and decelerate, so the exhaust system must flex with it. These engines are equipped with a front exhaust pipe with a flexible section, which accommodates this movement. When replacing this pipe, you must cut the old pipe between the flex section and the Catalytic Converter. Purchase a new front pipe from the parts store, and with it a short "coupling" piece which will be slightly larger in diameter, so to fit over the two pieces. You will also need two clamps sized to fit over the coupling. Install the new front pipe, with the short coupling at the joint with the old section just forward of the converter. You then clamp the two ends of the coupling to complete the repair.
Have someone check to see if there isn't wiring or something else that is up against one of the exhaust manifolds. It could lead to a short/fire. It could be the catalytic converter
Short answer: YES! Longer answer: The EGR valve is designed to recirculate some exhaust gas into the intake, in order to cool combustion temperatures somewhat. If the combustion temps exceed 1100 degrees (actually common in gasoline engines) then oxides of nitrogen are produced. these gases are what we see as visible smog. If the EGR valve fails, it can lead to very high exhaust temps which can gradually melt the insides of the catalytic converter. If a failed EGR is combined with a lean fuel mixture, or over-advanced ignition timing, the melting of the converter happens very quickly.
It can last the life of the vehicle. But it can be destroyed by an engine not running properly in a very short period of time.
It most likely has a plugged catalytic converter.
Generally, unburned fuel getting into the converter is what damages them. How is it running?, what size engine? What did the dealer say is "wrong" with the converters they are replacing? -->You can easily damage your catalytic converter by making a lot of very short trips and not allowing you car to properly reach operating temperature.
You will not obtain any further horsepower or torque in this application by removing the catalytic converter. Many individuals read on "import tuner" magazines or websites that "gutting" this allows more power by making the exhaust stream "free-flowing." The truth is, none of these "tuners" know anything about the engineering behind the catalytic converter. The catalytic converter has materials inside of it that are catalysts, which start and speed up the chemical reaction in the converter without being damaged themselves. These materials are cerium, platinum and palladium. In short, they strip NOx into harmless O2 and N, which reduces pollution into the atmosphere. While stripping NOx down with the intense heat in the catalytic converter, this also burns remaining HCs in the exhaust stream, further reducing emissions. All in all, the removal of the catalytic converter will not produce any extra power for two reasons: 1) The exhaust stream will not be any more free flowing; the catalytic converter is not restrictive, it simply acts as a "catalyst" to reduce emissions, and the engineers of the vehicle have designed it that way. 2) Removal of the catalytic converter can disrupt the air/fuel mixture actually inducted into you engine, and here is how: Let's say you remove your catalytic converter for "more power." The PCM of your vehicle determines how much fuel to deliver with your air stream to your combustion chambers based on input from various sensors, such as the MAP, MAF, and HO2s. Now, with your catalytic converter equipped, the chemical reactions are occurring and the heated O2 sensor(s) will detect X amount of oxygen in the exhaust stream, and the computer will say, "okay, you're running like this, inject fuel for X amount of milliseconds this time." If you have upstream and downstream heated oxygen sensors, or even just upstream, let's say you remove your catalytic converter, and the HCs don't get burned up in the cat since it is not there. Now you have lots of fuel molecules going down the tailpipe. The oxygen sensor(s) then see minimal O2 since there is excessive fuel vapors. The PCM says, "WHOA, WAY too much fuel in the exhaust stream, the engine MUST be getting too much fuel (when in actually it is the absence of the cat making it LOOK like there was too much fuel), so let me lean it out, and turn injector on-time WAY down." All of the sudden your vehicle has NO power, all because the removal of the cat tricked the computer to put much less fuel into the engine, so you are running a very lean air/fuel mixture, and you have your pedal through the floor, and are hardly going anywhere. All in all, if you are going to perform a "tune" or modification to your engine, it is wise to understand how all of the systems and components interact with each other. Lots of idiots think they know everything because they read "Tuner Monthly" and then they wonder why their vehicle doesn't run right. While a lengthy explanation, I hope this answers your question.
I would guess that your catalytic converter is plugged or your oxygen sensor isn't working giving you too lean of a mixture. A shop owner once told me he checked for a plugged catalytic converter by removing the oxygen sensor and driving it AA short distance to see if power was restored.
ok, this was my question, but no one answered it so I figured it out myself. Apparently, the OEM exhaust system for Tercels does not have this wire, so my theory that it was a grounding wire of some sort was debunked. The parts guy did not have a clue either, and then it dawned on me that this welded wire connected to a hook on an unused bracket post has the sole function of temporarily holding up the rest of the exhaust system while its being assembled/disassembled. Hope this helps someone.
Short answer timing belt... Long answer The lightweight pressure-cast aluminum cylinder head's exhaust ports are on its front side (vs. the previous engine's back-side ports) so the close-coupled catalytic converter can mount directly to the head without a separate exhaust manifold. The dual overhead cams (with improved journal finish to reduce friction) and four valves per cylinder are driven by a silent chain with a friction-reducing double-arm tensioner. A pair of chain-driven counter-rotating shafts in the oil pan take care of the second-order harmonic vibrations common to I-4 engines.
it is a spinning air pressure powered tool that has the "exhaust" port for the tool on the front side, compared to the bottom or rear. it is used for high speed grinding applications where a larger, more cumbersome electric grinder may fall short because of lack of space.
Front mid Short Sound. :)
kat a lit ik - all short vowel sounds
A ductless exhaust provides a short channel for the airflow to pass through, while a ducted exhaust provides a pathway to move the air far away.
The first thing that comes to mind is the catalytic converter plugging up after driving a short distance and clearing itself after sitting for a period of time. Take it to a muffler shop for an expert opinion. The plugging of the converter would cause a huge power loss and the resulting restricted exhaust gasses would cause your check engine light to come on since the oxygen sensor would be giving the computer bad information.
Short on the front, long on the rear.
The short exhaust should be more efficient and increase power.
