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 Fat Daddy Pipe \u0026amp; Y-Pipe, Stealth Head Kit, ECU Flash, Hypershift Clutch Kit, and High Flow Intake.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Fat Daddy Pipe \u0026amp; Y-Pipe 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. The High Flow Intake opens up the restrictive stock intake plenum to round out the package. You can use all of 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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eYou must send your ECU for programming, and Cylinder Head for exchange!
