Speedwerx Stage 2 Exterminator Kit // Arctic Cat 8000 C-TEC2 Snowmobiles

The Speedwerx 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 Single Pipe and Y-Pipe, ECU Flash, Stealth Head Mod, VForce Reeds (2018-2019 only), Hypershift Clutch Kit, High Flow Intake Vents, Aluminum Panel Vents, and Exhaust Valve Cable Gauge. The Stage 2 delivers 12-13hp more at the peak, and 16-17hp more in the midrange, and you'll also save 13.9 to 18lbs when combined with one of our lightweight mufflers!

Our at Fat Daddy Pipe and Y-Pipe was the clear winner among the 5 major aftermarket brands tested by DynoTech Research last season. Not only does it help make power, it's 4.5lbs lighter than stock too. We also have a high elevation specific pipe for better performance at altitude, or an optional adjustable pipe with interchangeable stingers if you regularly switch between high and low elevation. The pipe is just one part of the performance equation though. Now available for all 2018-2021 models, 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. We tested numerous reed designs in 2017, and settled on a special design from VForce that proved to be better than all others on the 2018-2019 engine, while the 2020-2021 kits work well with the stock reeds due to the different OEM cylinder and injection design. 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 Intake Vents deliver more cool air to make more power, and the Panel Vents help keep your belt and clutch temps in check. The Exhaust Valve Gauge is an easy way to check cable lengths to ensure they are in spec to eliminate any potential running issues, something that's often overlooked on these machines. Add our standard Lightweight Muffler that's 9.4lbs lighter or the L2 Series that sheds 13.5lbs, and you'll save 13.9 to 18 pounds overall!
We also offer a Stage 1 Exterminator Kit for a little easier installation at a lower price point. It does not include the Stealth Head or VForce Reeds so the power gains aren't as strong in the midrange, but it's noticably better than stock with the same 12-13hp peak power gain. If you find yourself wanting more, you can always upgrade to the Stage 2 spec down the road as well.
