5 of 5 Let 'er breathe May 30, 2022
Reviewer: Coyote from Rio Dell, CA United States  
I installed this dual port muffler on my new Holzfforma G660 PRO that I'd put three tanks of gas through and what and it makes a noticeable  improvement in wide open power, even with the 36" bar buried in 40"+ log. Stock was kinda sucky, but now it's the beast that Stihl designed it to be and it's bound to get better after the saw is set in. Easy to install in about 10 minutes R&R. Hyway made in Taiwan means high quality at an affordable price.

4 of 5 Dual port and has spark arrestors September 6, 2021
Reviewer: Ed O' from Canton, MA United States  
It has dual outlets and spark arrestors which the kit one does not.  I kind of like the looks of the kit one better, but hopefully this will flow more and the spark arrestors will let you cut places that mandate they be in place if that is a concern.

Reviewer: WiZenUp!! from Sykesville, MD United States  
Muffler is robustly built and obviously better than the item it replaces on my clone saw. Thicker, with better engine breathing and structural integrity.
