What are the advantages and disadvantages of using a tuned pipe on an OS.65 LA??
This engine is a dog with a 12x7(9120rpm) so I want to increase its power with THIS prop.
Thank you.

Kostas,
I wrote to you that your engine should spin at 11,000 RPM with this prop, as did this same engine, in the MAN 03/05 issue multi engine test, on 10% nitro.
The performance of your engine is particularly substandard.
A tuned-pipe should not be installed to treat a malady of an engine, but to increase the performance of an engine, which is in good condition and is producing its maximum performance as it is.
If your engine was getting 11,000 RPM, a properly set muffled pipe would bring it to 12,200-12,500 RPM.
You should contact BAX in the OS support forum, as your engine is currently producing only about half as much horsepower as it should.
