We highly recommend our Exterminator Kits to get a complete bolt-on performance package developed on our dyno and thoroughly field tested to meet our strict performance standards. The Stage 2 Exterminator Kits are the ultimate choice for those wanting maximum power and performance in a naturally aspirated, stock displacement bolt-on package with pull and go reliability on pump gas. The Stage 2 consists of our Pipe Mod, ECU Flash, and Hypershift Clutch Kit. The Stage 3 spec adds our Stealth Head Kit for High Elevations.

Our Pipe Mod is the key to making big power, but that's just one part of the performance equation. Our ECU Flashes that are developed in-house change the fuel and timing parameters to ensure you’re getting maximum power and excellent throttle response with pull and go reliability on pump gas. Our Hypershift Clutch Kits keep the revs in the sweet spot to get all that added power to the ground when pipe temps and RPM’s climb on a long pull across the lake or up the mountain. The Stealth Head Mod has our interchangable billet domes with a special chamber and cooling design to reduce the chances of triggering the knock sensor to keep you at peak power all the time, and it also enables those riding at higher elevations to safely bump up the compression on premium pump fuel as well. You can use this in conjunction with your stock muffler for quiet power, or add our standard Lightweight Muffler that's lighter than stock for a liitle better sound at a level reasonably low for everyday trail riding, or the L2 Series Light n' Loud Muffler for the lightest weight with an aggressive race sound. 

We also offer a Stage 1 Exterminator Kit for a lower price point option. It does not include the Pipe Mod so the power gains aren't as big, but it's noticably better than stock. If you find yourself wanting more, you can always upgrade to the Stage 2 spec down the road as well. 

Sending us your ECU is always the easiest and preferred way to get it done, but for those that wish to purchase a tool to flash their own ECU, we are using the new industry leading EZ LYNK Auto Agent 3 system. This will not only allow you to flash your ECU but you can also do much more.
