looking for a good performance boost package that includes new pipe, air filter, carb jets, etc. anyone know of the best for the money for the 06 rancher 400 AT?

 

highlifter.com has some overbore piston kits, high compression and stuff. Remember, by adding more power you'll put more stress on engine components, so it will wear out faster.

 

Hey Sauce,

I have a uni filter on my o4 AT now and just ordered a HMF Eco exhaust and a Dyno jet kit the other day. When I get it installed I will write back to you to let you know how it all works out. I know I could have bought the Utility series pipe from HMF a little cheaper but I didn't want an obnoxiously loud quad.

 

Thanks Yoda, I'll be curious what you think about the changes.
