Note: The ECU Flash is being finalized and we will notify you when to send in your ECU. It is safe to use the Stealth Head and Clutch Kit with the stock ECU Flash in the meantime.

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 1 Exterminator Kits are a great entry level package that includes our Stealth Head Mod, Hypershift Clutch Kit, and ECU Flash.

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. 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 2/3 Exterminator Kits for those wanting a little more. They includes our Pipe Mod and a different ECU Flash for maximum power and performance.
