Hi.Cat effy is usually a problem associated with a tired old converter. Clear the codes.and test drive. And try your stock h pipe.If possible. Unless the 3 inch wont hook up to it. Does it have mil eliminators. Try checking them.They plug in to the rear o2 sensors. Sounds like it may be sensing to much flow. U have a aftermarket high flow on now. So i doubt its clogged.9000 miles shouldnt clog it up.
