Fits all 2004-2006 Arctic Cat ZR 900, Mountain Cat 900, and King Cat 900 models. A fuel controller is not required for EFI models, just remove the airbox shelf. Carb models require rejetting (jets not included) You must use premium (91+ octane) fuel on all years and models with this pipe.
NOTE: We originally supplied this pipe with a y-pipe, but they are no longer available so it may be slightly less than the 10-11hp gain as tested with the y-pipe and the jets may need to be changed from the original spec.
ABOUT OUR EXHAUSTS:
All of our Fat Daddy single pipes undergo countless hours of testing and development combined with hours of design and fitting. We have taken the time necessary to produce the best single pipes for your machines. Here are some of the key benefits to using our single pipes:
STRAIGHT-UP USA HORSEPOWER
Every pipe is designed, DYNO tested and then field tested to produce real, accurate and reliable horsepower gains. Our pipes are not built for one run across the lake or on the trail. Our pipes are built to last and our pipes work!
All of our single pipes come with a long lasting finish that offers a great look while also acting as a thermal barrier to keep heat inside the pipe for optimum performance.
All of our single pipes are lighter than the stock system. You can expect an average weight savings of about 5 lbs.
All single pipes are designed to run into the stock muffler for simple installation.
You can expect stock sound levels while using the stock muffler.
Each single pipe comes complete with a full instruction/set-up sheet which includes jetting specifications if needed, clutch set-up suggestions, as well as full installation instructions.
