I know the term "critical muffler", but does this imply a design, or a
performance standard?
Are critical mufflers available for small engine applications, ie., in
compact packages for 1.5" exhaust pipes on small air-cooled diesels?
Suppose I add a critical muffler to a small, unbaffled, aircooled diesel
rated at 77dB/23 feet?
Will it provide significant additional quieting, given that the engine block
radiates significant noise?
