    just bought a 2001 carry automatic 4x4 looking to do a few mods, air box mod to increase air flow and remove or take the guts out of the catalytic converter and maybe a different muffler.

    Think this will add more power or hurt the performance?

    good idea take off catalyltic converter and throw as far as possible . you could also add a blower for air that runs off crank. wow now your cooking

    Leave the cat... But ditch the stock muffler Maybe look at a k&n filter.

    I've heard those small cats like the one on my truck are very restrictive though? Yeah I see a k&n filter in my future

    I would leave it, cats have not been that restrictive since the 70s.

    With a more free flowing muffler I find my hijet has a little more up and go but best of all it is better on big hills and takes way less peddle to maintain speed

    I am also running 13 inch rims and the tires are about 7% taller and the engine notices the loss in torque

    You could always swap in a 1.6 out of a geo tracker

    I put on a walker muffler the same as fupa put on his. I also found a k and n filter that fit by using the filter look up by size on their website. Another thing would be a bit more timing advance, I dont have my timing light ATM so I can't try advancing my timing yet.

    Not having any experience with ATV's, do you think it will be louder - same - quieter?

    Depends on type of muffler, if it's a race ish type of muffler yeah it'll be louder but they have performance mufflers out there that are quite

    I've seen several folks use a OEM take off sport bike muffler. They can usually be picked up on craigslist or ebay cheap.
