maybe the auto mines computer has a bit to do with it. Wat plug on the cat converter??? never seen that b4, theres a sensor on the standard dump pipe and that could also b ur problem if its been cut off (maybe they wanted a lumpy sound like theyve done cams).........go to a mechanic who knows his stuff get him to check it out
