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.
