What yall think about doing the Poulan Pro PR5020 50cc muffler mod where you drill a ½” hole between the 2 screws in the muffler? Saw it on a YouTube even with a side by side comparison but my old damaged ears couldn't tell the difference. Plus if someone was trying to prove a point they could easily push down harder with the one saw they wanted to win the comparison. Your thoughts? Thanks for your time and sharing your experience.
