Cayman R question, I have searched the database not finding exactly the answer.
I have a pretty audible rattle left side exhaust system. Thought it was a heat shield, but Autoform in Vancouver took the car apart and they say catalytic converters, plural. Left side far gone, right on the way. One expensive solution is to use Porsche parts through Porsche Vancouver which equals $7K CDN for the cat units and associated parts, plus labour. There are Porsche parts to be had elsewhere for somewhat less.
