Depends on how it is bad. A catalytic converter can break down internally. The structure inside is a ceramic honeycomb coated with metalic chemicals. If the honeycomb fractures due to rough road driving or the unit is struck sharply by a protrusion in the road you can have two outcomes. The exhaust might flow freely out the tailpipe or the fractured internal structure blocks the inlet pipe causing back pressure and reducing engine effiency. Another cause of failure is wrong fuels or bad timing that over time causes soot buildup in the inlet reducing flow and causing hard starting and rough engine idle as well as poor performancs/mileage.

confident, actually if the converter isn't plugged. while converters are plugged the motor won't run in any respect or run like crap! information Flash! do no longer replace the converter till ultimately a Nissan broker says that's undesirable. If yet another converter is needed, a Nissan broker isn't the situation to purchase it. NAPA automobile aspects shops have Walker Direct greater wholesome Catalytic Converters for hundreds of greenbacks much less.

It may not affect the way the car runs. What it will do is it will make your car fail a smog test. The reason I know is I had to get my catalytic converter replaced because it would not pass a smog test. It wasn't cheap, either. The car ran fine. Actually it ran better with the old catalytic converter, but it's the emissions that are the issue.

If the car is 1996 or newer it has OBD 2 which has an O2 sensor before and after the cat. If the cat is bad the O2 sensor will detect it and send a signal to the cars computer allowing it to make changes in the cars fuel and air mixture to try and compensate for the bad signal it recieved.

Most cars run better without them but they all have them and have had for years. Take it out and replace it with regular exhaust pipe to the muffler. Even if the catalytic converter isn't the problem, it'll run better when you get it properly diagnosed and corrected. One major issue: You or a friend have to do the work yourselves; it's a $10,000.00 fine if an auto shop/muffler shop gets caught doing it so none of them will. I took the one off my '92 DeVille and it runs better, sounds better, and gets better gas mileage. Good luck w/it

id agree with the person above my post. i have a testpipe on my car right now. gas mileage is crap.
but cloged cat can make the check engine light come on. also it will make the ecu go crazy if it senses somthing wrong. if you get it replaced. im not completely sure, but i think you would need a certificate as to why u need to replace the cat. im not sure if thats the new law or for new cars.
