Speedwerx Exterminator Kit for Ski-Doo 850 E-TEC
Our Exterminator Kit combines our ECU Tune, Exhaust Pipe Modification, your choice of Standard or L2 Competition Series Lightweight Ceramic Coated Mufflers, Hypershift Clutch Kit, and Panel Vent Kit in one convenient package. The ECU Tune and Pipe Mod will unlock maximum power and performance, the Muffler shed 6.5-9.95lbs and sounds great, the Clutching puts the added power to the ground, and the Vents help keep the underhood temps down. Track Dyno testing has shown a 8 to 9.5hp gain- 77hp stock to 85-86.5hp tuned and clutched. That translates to the performance equivalent of a 16-19hp gain at the crankshaft!
Kit Includes:
- - Speedwerx ECU Tune
- - Exhaust Pipe Modification
- - Standard Lightweight or L2 Competition Series Muffler
Our Lightweight Muffler cuts 6.5 pounds while maintaining a very trail-friendly sound level, and the L2 Series (Light n' Loud) Muffler sheds 9.95lbs with an aggressive race sound.
- Hypershift Clutch Kit
Clutching changes are essential to put all that newly added power to the ground! Our kit includes Speedwerx Machined Weights, Weight Adjustment Kit, New Clicker Adjusters for More Fine Tuning Options, H5 Alloy Drive Spring, and a Custom Cut Helix.
- Panel Vent Kit
Our vent kits install on the front side of the panels to draw cool air into the engine compartment- this helps keep the clutches and belt cooler by lowering the overall temp, and it's especially helpful on the turbo models that generate a lot more heat under the hood. They are made from laser cut aluminum for durability and look good with a Black Anodized frame backed with stainless steel mesh to keep the snow out. Kit comes with two vents, rivets, and installation instructions.
About ECU Tuning:
Throughout our extensive R & D experience, we found that recalibrating the ECU/ECM is the best way to get the most out of your machine. We do this by taking the time to go through the entire ECU and optimize it from the ground up. Something that was not commonly done in current ECU tuners. This way we can tune it to as close to perfection for every scenario to outperform your current programming configuration. Your machine will be tuned and perform just as well as a machine that was on the dyno and tested for months on end so that it excels in every situation to be smoother, faster, more efficient, and more reliable.
You must send your ECU to us for programming and Exhaust Pipe for modification! Please include a copy of your invoice or a note with your return address and order number. The return shipping cost for the service of your choice will be added when purchasing online.
