A Catalytic Converter is a Catalytic converter. They are all the same. They all have to blow good numbers to pass smog so they are the same. Go talk to your local muffler shop they will tell you. Thats what the guys at muffler time told me anyway. So if you really want some sound go with an offroad exhaust system. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
