    So a little update

    I knocked the guts out of my cat, helped throttle response
    I picked up a small tractor muffler (haven't installed yet)
    Also have a k&n filter on the way
    And E3 Spar plugs on the way

    Okay another update muffler is on sounds okay e3 spark plugs installed waiting on k&n and it'll be done ( for now ) lol.

    Probably jump up to a higher octane fuel to accommodate the hotter plugs .

    Definitely made a power difference for sure

    So what muffler did you all find?
    I just got a 91 MDb51T with the 660.

    Has anyone ever gotten there hands on a Arctic Cat 660 turbo motor? Its 125hp!
    Even the non turbo motor is 80hp!
