Muffler for yanmar 4lh ste

[gohelm]

I am looking for a way to reduce the noise of my yanmar 4lh ste. Does anybody have experience 'muffling' it? The main concern i have is to reroute the 102 mm 'boa constrictor type' of exhaust piping. I know Vetus has a rather compact and easy to install muffler but i am not sur whether this one will be effective. Any thoughts/experiences?

Best regards Gabor

Vetus stuff works really well. Install their muffler, I'm sure it would work fine.

Thanks feedback...think we have a rather rigorous change of plan for our project unfortunately by changing the whole engine configuration (but which also solves sound issues) but will keep this in mind
