    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!

    I just used a tractor muffler on mine , as far as the artic cat motor every thing I've read says it won't work without a lot of $$$$$

    I plan on just using the EFI system to increase the HP to 80hp!

    Hey do you have a picture of the exhaust after installation? How easy was it to retrofit?

    I would like to know what size the exhaust manifold flange is?
    At the moment I want to try and remove the Cat and just make a flange to go straight to a 2" pipe?

    I have a 2001 carry as well.. db52t. was wondering about getting a turbo. has anyone ever found where to get one, or installed one before? they do have turbo models out there so they must exist
  13. Has anyone messed with their EFI set up? Or tried a performance chip upgrade?
