So, I got the universal cat from Advanced Auto and put it on a couple months back. The car has been sitting since then, and I only started it up very quickly once after I replaced it. I know that everything isn't clamped down perfectly. I had some issues and I apparently didn't cut the piping to the right size for after the exhaust went back up, so it's lose. But, today, I started it up and the cat caught on fire! There were flames coming out of the end of the pipe over the original exhaust and the end was red hot. Any ideas? One of my roommates said a possible oil leak into the cat? But, the oil is still at the same level it was when I parked The Beast ... and when I took the old cat off, there wasn't any oil or anything inside or anything leaking out. Is it possible I got a defective cat??
