Description of Change: The strength of the material is increased for a new exhaust pipe. The new exhaust pipe is coated with a high temperature paint. The improved paint and the strengthened material prevent the exhaust pipe from premature rust.

Adaptable To: The new exhaust pipe and the former exhaust pipe are listed in Table 1. The effectivity and the adaptability of the new exhaust pipe is listed in Table 2. The new exhaust pipe is adaptable to the models that are listed. Replace the former exhaust pipe with a new exhaust pipe, if rust has decreased the durability of the exhaust pipe.
