Yep, there are mods. My Poulan Pro 220's muffler is dual ported. And it is now smoking stihl 250's (250's are stock). Stock it was a dog, now modded it is awesome.:greenchainsaw:

I recently had a 4620 given to me it had the restrictive crimped muffler on it.
I ordered a old style black two piece muffler for it that I modded.I drilled the holes in the baffle to 7/32 and added a extra 5/16 hole in the corner of the muffler right next to the stock opening that is much larger on the Black muffler. Other than the sound and performance you can't tell by looking at the saw I did anything to it!
I found if you take the baffle out you lose strength in the muffler as the muffler bolts run through the baffle. Leaving the baffle in lets you tighten down the bolt against something solid.Without crushing the mufflerI took the baffle completly out of mine.:greenchainsaw:
