chainsaw performance pipes

Custom muffler for MS660/ Stihl 066/Stihl 064/ 661 chainsaw models. these power pipes are very impressive there 11 to 12 percent more gain and keeps your saw from heating up there a great job made from stainless steel you just get the pipe not the saw call 0874 007 501 I would also like to say there's a lot of hours go's into building a pipe and a lot of time spent getting them right the work realy good on the 661 it's fast and easy to do the M tronic reset I CAN DO POST 📫
