rattling noise coming from cat converter
ive got a 97 lt1 dual cats passenger side cat is rattling like crazy at idle and a little when driving, i checked the brackets and it is not loose, i have a stethescope and it sounds like it has a rock bouncing around in there. is there something in the cat that could break loose and do this? i dont know how anything could have made it through the valve train without breaking something and the engine runs and sounds normal.
