    You're exactly right. That's a big draw back on the Baileys muffler. Stihl knew that the screen flowed less than the same area without a screen, so installed the screen in a way that it had much more surface area. That way the screen would not be a bottle neck. On the Baileys muffler, your outlet hole is going to have to be much larger in order to get enough screen surface area. I recommend you use your original muffler body and the new cover. There's no need to even mess with the baffle in the OEM muffler. Open up the exhaust outlet as much as the deflector will cover. Finally, open up the port on the muffler cover.

    I did the same mod to my 460 with the Bailey's cover, I cut the front of baffle completely off, opened stock port to double its size, and installed cover. I am happy with mine. I did have to pull limiter caps and retune carb with this setup.

    looks like the port is still part open and there a shadow or something maybe some oil blackening on the roof of that port,looks normal to me

    Thanks for the replies everyone. Sorry that I have been away from the thread for a few days.

    I guess I should have done more research before buying the muffler from Baileys.

    The good news is that the muffler combo was the same price as just the cover (when I ordered it).

    I spent some time working on the NWP muffler this weekend and below are pics of how it came out. I didnt take a pictures of the cover before opening it up but the black paint on the screen outlines the original opening.

    Should I open up it up more?











    My next question is about the gasket. The one I ordered from Baileys looks like a rubber/composite material while the factory one is metal. Is there any reason not to use the factory gasket again? Is it directional?






    From searching around, I figured that I would need to pull the tabs and adjust the carb, just need to spend some more time searching around here to figure out how.

    Thanks blsnelling,

    I will do this with the OEM, just needed to practice a little on the NWP. I am reading reading alot of your threads/posts and they are very helpful. Currently reading this one.

    Ok, got the muffler back on. I decided to use the OEM gasket since it didn't look damaged. Just waiting on the tool to remove the limiters.

    Cleaned the air filter, have a new RSC chain, fresh gas, and some test wood to use while tuning (17" diameter oak). I will work on a log stand over the next few days.

    When I pulled off the air filter cover, there was a black divider blocking off part of the air intake. I removed it, figured the more air the better....

    That black plastic shutter

    ''When I pulled off the air filter cover, there was a black divider blocking off part of the air intake. I removed it, figured the more air the better..''

    That is installed for summer time use,stops it sucking hot air from engine.
