What is the best muffler to use for the best performance and reliability on an OS 1.60?
Pitts, Stock, etc

Thanks for any input.

They are not very picky

imho, the stock muffler will give you the 'best' results in terms of power and trouble-free performance...i like to mount my engine at the '45-degree invert' position, which places the muffler centered under the nose...most other exhaust systems (like a pitts) might reduce muffler pressure, and require installing a pump...so far, i haven't had to do that...hope that helps...ken

That's a nice install Ken.
