I have a 2000 Prado 90 5VZ-FE 3.4 Petrol, was my fathers car. He never replaced the catalytic converter nor do I. The car has 145000KM, the question is: The cat could be clogged? Should I replace it with a new one (MagnaFlow o something better than stock)? The quality of the fuel at my country is not as good as other places.

Welcome Mauricio! :thumbup:

It is very possible that it is now clogged with that mileage. It needs to be replaced but if you don't have emission control requirements in your country you could just cut it out altogether.

Hi! Just updating the post, yesterday I remove the cat, and yes, it was clogged. Gonna wait until next emission rev to put a new one. The car feel a lot different now.

Thanks again!

Removing it will definitely improve the performance, especially if it was clogged. :winkx:
