Review on Sierra International 18 4457D Exhaust Protector by Marvin Breezy

Revainrating 5 out of 5

Works great with valve parts

Bought to fit my '91 Ski Centurion Falcon after one of the exhaust flaps broke in half due to brittleness due to age. The rubber is very thick so it will last for years. This makes it unwieldy, especially compared to baffle plates that run in the exhaust port, but it does the job (preventing backflow into the engine and allowing exhaust fumes to escape) and it sits below the waterline where no one can see it, so who does it To care. . Good price compared to other exhaust valves.

Pros
  • Includes: Stainless steel clip
Cons
  • Not sure
