what coul happen?

Hi, i been thinking in remove both CATALYTIC CONVERTERS of my 2000 maxima and remove the inside material to allow more air flow, but i didn't know if thi action could result in any kind of malfunction....
any comments will be apreciated...

thanks ..

do you really want to hollow out 500 to 700 dollar each converters? expect a check engine light and hope you don't have to go to inspection

Test with piece of straight pipe - later u want (?) to re-install the cat's.

If youre after more pwr, go after air intake.

thanks, but i live in mexico, here is not ilegal remove the cats, but my concern it's about the mpg, power, torque, diference with out cats...., and maybe if i adapt any sensor the cats contain outside to a straight pipe the SES light perhaps doesn't come on...
