the federal law says that it is illegal to remove a functional catalytic converter. Also, you are required to have the same # of cats that the car came with. on the other hand, who worries about the federal standards? lol
I have to. here in upstate NY where I live, people care little about cat.During inspection, they won't even look under the car. But I'm moving to Ohio sometime this year. Where I'm moving to, have E-check, with Visual check. Even with Cat, it won't pass visual. So i guess I have to go with BBK shorties when it come out....
