The 1994 -1996 Toyota Camry has a flexible joint inline with the Rear Catalytic Converter. (Yes two converters!) The Flex joint develops a leak and then the vehicle sounds like a tank driving down the road. The Flex joint is welded onto the pipe so it is not replaceable. Fortunately the cost for the entire pipe with the converter is very reasonably priced! Replacing the entire Converter pipe will have the vehicle back on the road in very little time.
