I've been reading the forums here and have seen discussions about whether or not there can be gains made by modding the 455's muffler. Any suggestions? I have had mine for 2 years and have cut about 4 cords of wood with it. I just purchased a smaller 18" bar and blade without the safety chain it came with. Can some exhaust mods and fuel enrichment give me more power, or am I better off leaving it alone? Thanks for any help
