Does a catalytic converter increase horsepower?
The amount of horsepower you will get from a high flow catalytic converter depends on your engine and the modifications you have made to it. You may see a horsepower gain of as little as 5 hp or as much as 60 hp. You may also get an extra 5-60 ft lbs of torque.
What does a catalytic converter do on a Nissan Frontier?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Frontier’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
What are the signs of a catalytic converter problem?
Signs of a Catalytic Converter Problem Engine accelerates poorly or is hard to start. A sulfur or “rotten egg” smell indicates the formation of hydrogen sulfide (H 2S), a likely sign of catalytic converter contamination. If the catalytic converter’s housing is discolored or warped, there may be internal leakage or overheating.
Why are catalytic converters so restrictive on cars?
The catalytic converters in the past were very restrictive because the exhaust coming from the combustion process was extremely toxic. Modern engines create less of an impact, which means the device creates almost the same effect as a straight pipe for the average vehicle on the road today that is less than 10 years old.
How are rear sensors used in catalytic converter?
The (downstream) oxygen sensors are only used by the ECM to monitor catalytic efficiency by comparing the signal to the upstream sensors. The rear sensors have no affect on engine performance nor fuel management.

Is the catalytic converter part of the exhaust system?
Benjamin Jerew is an ASE-certified Master Automobile Technician with over a decade of experience in auto repair, maintenance, and diagnosis. The catalytic converter is part of the exhaust system, processing all exhaust leaving the engine before it can escape into the atmosphere.
Is it possible to fix a catalytic converter without replacing it?
You may be able to fix your catalytic converter without replacing it using one of the following methods. Today’s automobiles are cleaner and more powerful than ever before, thanks in no small part to electronic controls and emissions control devices—including catalytic converters.
What is the diagnostic code for a catalytic converter?
An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator.
