Rocky81 Posted November 6, 2010 Report Share Posted November 6, 2010 Hello my catalytic converter is shot on the passenger side. Its making a loud rattle and sometimes blocking flow. What options do I have to fix this beside replace. I am in an area with no emission tests. Thanks Quote Link to comment Share on other sites More sharing options...
