STEALTH HEAD MOD // 2014-2025 Arctic Cat ZR / RIOT / XF / M 6000 - 600 C-TEC2

What we do is machine / gut your stock head so that you can run our interchangeable billet domes. These domes drop right into place under the modified stock head cover without anyone even knowing it! Not only does this add some serious power to your machine, but it is a cheaper alternative to a complete billet head kit setup. We are seeing 4-5hp gain at sea level, and up to a 8hp gain at higher elevations on premium pump gas. These are an integral part of our Exterminator Kits to maximize the power and performance of your machine!

Update Jan 24: In testing on the new Catalyst models we are not seeing any significant gains at lower elevations like we are on the previous models, but they are working great at high elevations- the increased compression really wakes up the bottom end and throttle response on these machines.

Note: the base price is for the head mod only with exchange of your stock head, you must order domes and o-rings as well.

Core Options:

• 1. Send us your stock head core and we will send you the Stealth Head once we receive it. We have modified head in stock and ready to ship, no waiting for your head to get machined.
• 2. Purchase the Stealth Head outright and we will send it out right away. You can keep your stock head, or ship it to us and we will credit you back when we receive it!
