If it is an exhaust leak that would be awesome, I hadn't gotten the gaskets so my mechanic made custom ones using a material which he said might burn away (on the outer layers - the middle was a metal) I think mine is leaking as I hear a slight ticking etc coming from the cats. Hopefully this is causing the CEL.
