This is the first muffler modification that I have done, mod at your our risk! This OEM chainsaw was stock until now, Wow! What a Difference this made, more pull with an over sized bar and chain combo, exhaust note, and over all performance of the saw in general, after the tuning the carb a bit. Remember that more exhaust flow, more fuel is required, do not forget to tune your carb to compensate for the correct air to fuel ratio!
