    so, I remove the four catalysts, and now the light "check engine" jump a error "catalyst system efficiency below threshold (bank 1) and (Bank 2)
    CODE : P0420 (bank 1)
    CODE : P0430 (bank 2)

    here we do not need a catalyst, so, what can I do, to avoid this error"check engine light"?

    now I feel much more power...& and the engine goes smoother...


    thanks in advance for the help..:)

    well...if you got rid of the front ones as well...which it seems you have.....you may as well just cover the light up, because im not sure there is a way to trick the cel after you have removed all 4 cats.

    no, now there are no restrictions on the exhaust gases..., the catalystdoes help for performance, is a brake for the engine..
    thanks for the tip from O2 Simulator...

    is correct that, but I have the muffler, the make a back pressure , and I have to put another pre-muffler, because the sound is very loud and tinny..., with that fix I the back pressure ,what the engine need...

    Here we do not have a dyno .. is very difficult .. the only Dyno, is at 500km from here, and is in Brazil and is 4x2 dyno.., not a 4x4 dyno...

    Is was only a comment that I put that... I know that I not need a 4x4 dyno for that.., I work with drag cars here...and Is always a problem, without a 4x4 dyno...
