Performance and fuel economy; these are the most common factors everyone seeks for in a car. Problem is, environmental concerns are often disregarded over drivability. Good thing though, is that your Nissan Sentra is installed with a catalytic converter; that not only improves your car's performance by giving way to better engine airflow, it also drastically reduces the noxious emissions from your tailpipe. To maximize the life span and reliability of the "cat-con"--as it is colloquially referred to as--make sure there is an ample amount of wash coat, and that the converter is always free from clogs.

Frequently Asked Questions

Ask APW
  • Can the Nissan Sentra run without a catalytic converter?
    Answer: Yes, it can. Although, no exhaust gas conversion will take place. Expect that your emission will produce a thick, black smoke. Also, the federal government prohibits all vehicles to run without a converter; this is also the reason why vehicles must pass an emission test before it can be given authorization to operate.
  • How to tell when a Nissan Sentra catalytic converter is clogged?
    Answer: Clogs happen because the catalytic converter accumulates chemical matter over time--this is perfectly normal, as long as the unit remains intact. If the Nissan Sentra won't accelerate when the gas pedal is stepped on, or when it totally refuses to start; the catalytic converter may be faulty. There is no need to replace the converter if the component is free from excessive physical damage. Clean the old unit first and test it out before finally deciding whether or not a replacement is required.
  • Is a Nissan Sentra catalytic converter easy to replace?
    Answer: An aftermarket catalytic converter is easy to find, but installing it will prove to be a challenge especially without sufficient mechanical experience. It will require detaching several parts of the exhaust system, and reinstalling them again in their proper places is tricky.
  • What chemicals should be avoided to prevent the Nissan Sentra catalytic converter from total ruin?
    Answer: The most common damaging compound is lead. Lead encapsulates the internal system of the converter; preventing it from contacting and treating the exhaust. A vehicle that is installed with a catalytic converter should only fill up on unleaded fuels to avoid contamination.
