is it possible to remove two of the catalytic coverters and can the other two do a proper job without them.

 

As I am sure you will told by more than one person here to remove or alter your cats is probably not a good thing to do. Aside from the fact that you will probably break numerous federal and maybe local laws, the effect on the computer cause more than one problem. i have heard of some guys that removed the cats with litlle or no problems but I think most would not recommend it. Good luck.

 

My advice if you want to remove your cat, is to make sure that you really know what you're doing, and that you really know what the effect and consequences will be.

As for any modifications, read read read as much as you can before doing anything to your truck. Listen to opinions, and read about the facts.

Good and bad things may result from altering or removing the cats so be careful.

I will not recomend this operation, I did it on my 98 Explorer it ran better but the engine light was on all the time I disconected the battery and the light will stay on so I decided to reinstall the cats and the problem was solved.
