It smells like burining plastic, right??? I have had that from like 9000 miles. With me it was the higher and more I revved it, the more it smelled. It seemed to have gone away for now, but it was annoying. I looked one time and saw clear gas coming out of the cat. I was thinking it was a ****ed up cat since my car was so low, but it wasnt. Im still confused. Maybe I should take out the cat and run a straight pipe. :thumbup:
