Default catalytic converters
As a follow up to my previous post "totally frustrated" has anyone had cause to replace the catalytic converters in their Cayennes?
Was the cause overheated exhaust?
Thanks

Is this in a V6, V8, or Turbo V8?

If a Turbo, then I would suspect blown turbos dumping oil into the intake, burning hte oil and plugging the cat.
