Welcome to the 90CC club.
Good advice on the DP, or open up the muffler in other ways.
IF you use non-Stihl chain you might want to get a high output oiler.
Stihl, in it's effort to please EPA, has tweaked the Stihl chains so the 660 adequately oils them, but just barely and they put on a small muffler. 660's sold in Australia COME with a DP muffler AND a high output oiler.
I've a pair of 660's which I upgraded the oilers and mufflers on:
		
		
	
	
		
	
and an 088
		
	
The 088 oils fine.
When you get these saws muff modded and ported they are an entirely different saw.
I wear ear muffs AND plugs, for silent sawing.
