Baileys online sells a muffler that I think is better than the stock ones. Anyone ever swap them out? The mufflers are $30 a piece. They also sell chain in 100' spools for $3 a foot. How do you make it work for you though? Do you have to have a special link to connect the chain to itself?
, so I picked up a few tie straps and presets. I go grab a six pack and come home with a 20" skip loop
. I don't think I'd ever buy a spool, though. Maybe if somebody was dumping them sooooper cheap.

Im a big fan of the dual port mufflers available for the 70cc+ Stihls. But iirc testing wasn't showing gains anywhere near what was being seen on saws like the 440 or 460. Seems the newer Stihls (461 was tested on a dyno) were breathing just fine through factory mufflers and were needing muffler mods only after porting.
