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
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
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
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.
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.
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. I am a Moderator on 'SnowmobileForum.com' 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 used an exhaust off a 600cbr i4 .works excellent! Good tone! I'll post a pic tomorrow of it installed.
