Okay, guys, I'm ready to start mod'ing the mufflers on all my saws. Since the 036 is such a wimp, that's where I'd like to start! I know some of you love your 036's, and my local Stihl shop says mine is running great, but I just find it pathetically under-powered. Time to hang some balls on it! Anyone got a diagram of the best mod's for this muffler? Should I run to the dealer and pick up a fresh muffler gasket, or anything else, before I start? My big question, having spent years building hot rods, is what I'm giving up at lower RPM's, by opening her up? I'd watch guys put free-flowing exhaust on cars with intakes and cam's tuned for low RPM torque, and then wonder why their cars were slower. If this goes well, I'll be doing the 064 and T435, as well.
