Snowcats never run right, ever! For those of you saying it sounds bad, sounds like both cylinders are popping. Although I'd bet on low compression and a cylinder. If I'm shopping sleds and see kiddo stuff like monster stickers I keep looking.
Those F7s are crazy loud with pipes. When did 2 strokes need to get louder? Go deaf riding those things as is. First time I rode a 660 Arctic turbo I was in heaven, made putting on miles much easier.
You got a nice setup though like the handguards make a big difference and u can use lighter gloves for more throttle dexterity. Also snow stuff rumble pack sounds nice too, not a hole lot different than the stock can but gives it that slightly better note. Also it is obviously lighter and gives u a slight boost in power.
Not everybody wants to spend a ton of money on a mountain only sled, and trailer. Some of us take what we can get, you big man you, with your mountain sled and fancy matching gear. You have matching gear don't you? You guys are precious
