I wanted to reach out to 430 owners to see if anyone has experience a cracked catalytic converter? For everything we hear about cracked manifolds, I was shocked to find I have a cracked OEM cat. On a recent drive I began hearing an awful rattling noise from the engine bay. I pulled the car over as quickly as possible and determined the rattle was coming from the area of one of the cats. I turned the car off and I inspected the cat and could see the line of a crack on the exterior surface. Has anyone else with a 430 had one of their OEM cats crack? Somebody had mentioned to me that since the cats are an emissions related part, Ferrari has to warranty them for 80,000 miles. Does anybody know whether there is any truth to this? How about repairing the cat by welding it? One thing I definitely don't want to do is go with an aftermarket cat as I prefer to keep things more stock and I have heard the aftermarket cat options are much louder and cause CELs, so I am trying to investigate my options with regard to OEM cats. Any experiences or advice is much appreciated?
