factory muffler 660...dual port?

[weatherby guy]

Attaching a pic of the muffler that came stock on my 660 and the 660 dual port cover. Given that the factory muffler appears to have dual ports how much of an increase (if any) can I expect to gain by putting on the other dual port cover assuming the carb is adjusted correctly. My saw has had 10 tanks through it thus far and seems to be running better and better. I don't want to mess up a good thing, however if more power can be gained with the other cover.....well. Thx

I have never seen one, like the one on the saw!
Dose it have a screen on the front cover?

If I'm seeing what I think I'm seeing,,,, uhhh that is not a factory dual port,,, Unless it is from Brazil or something,,,,, Help me out Lake,,,,

the cover thats not mounted is in fact a Factory Dual port,,,,,,,

can you take a close up of the dual port that came on your saw?????

I will try to get a better pic of the muffler later this evening. That said the only ports of this muffler are on the side that you can see. The rest of the muffler looks absolutely the same as any other 660 muffler that you would buy off the shelf today.

any performance increase possible with the other cover or am I good to go with what I have on it now?

 

[Trigger-Time]

Lake, would this also be off a non-USA saw?
