My dad went to order the muffler cover, and I told him to order the magnum one. He said he went to the shop and told them he wanted to order a magnum front cover for it. They told him the saw was not a magnum, without even picking it up and looking at it. It does not have an air filter where it usually says magnum on. He said is their an apperance difference? They said no. Than how can you tell. They said it is big enough anyway it does not need a magnum muffler. So I guess they ordered a standard one. I was cutting trails for 4 wheelers in my friends woods or I would have gone. I guess we will try to talk them into it again.
