Purchasing this product requires you to sign our Vehicle Compliance Waiver here.

We have built this kit to reliably extract the most horsepower from your new rzr xp 900. These parts are all tuned and matched together. We have extensive dyno tuning involved in our fuel controller map to ensure when you plug it in it will work perfectly.

Exhaust info:We offer our kit with three different exhaust options. We chose these exhaust because our testing has shown best results with them as well as being made for long lasting durability. Our Alba Racing slip-on and the Muzzys full system make about 1 more horsepower than the SLP. However the SLP is a few decibels quieter. If noise is a concern use the SLP. Both the Alba Racing slip-on and the SLP slip-on are maintenance free. The Muzzys will require occasional repacking.

Intake info:For sand only use K & N filters with outerwears.For all others use Uni filters.The inbox kit makes +1.5 more than the drop in filters due to the increased surface area.

Optional air box super seal. This is a seal that seals your air box lid to the airbox. This is not required but helps keep dirt out of the airbox. See pic.
