Speedwerx Stage 2 Exterminator Kit

Our Exterminator Kits are designed to offer you the biggest bang for your buck! What we do is put together a group of components that we have found to work the best on each and every machine to get the best performance at a reasonable cost.  The Stage 2 Exterminator Kit for the 2018 Wildcat XX comes with our Speedwerx L2 Series Stainless Steel Slip-On Exhaust, Stainless Steel Exhaust Header, Hypershift Clutch Kit, High Flow Air Intake, and a Dynojet Power Commander V Fuel Controller. You can also select the optional Q6 Stainless Steel muffler is you want a quieter, maintainance free muffler. ECU Flash now available! This eliminates the need for a piggyback fuel controller and adds some cool features including Raised Speed and Rev Limiters- see full details below. 


Stock XX vs. Speedwerx Stage 2 Exterminator Kit-





Update 4/12/18:
The Textron Off Road Wildcat XX’s are starting to show up at dealers around the country, and naturally everyone is wanting to know more about Speedwerx performance upgrades as the machines filter out into the hands of the consumer. We’ve been working on a number of bolt-on parts and dyno testing many different configurations over the past few weeks, and we were pleasantly surprised to see the XX pull 130hp for a stock baseline number, 5hp more than the factory rating. Even better yet, our Stage 2 Exterminator Kit delivered 142hp with power and torque increases over the whole RPM range. Take note of the huge gains at the lower RPM range as well, 12-18hp more over a 1000rpm+ spread, that translates into more grunt down low to get you out of the hole quicker- it’s really noticeable just by the seat of your pants when you mash the pedal. All testing was done with 87 octane fuel, so you can save a few bucks at the pump too.


- Speedwerx L2 Stainless Steel Slip-On Muffler- The L2 (Light n' Loud) Series Stainless Steel Slip-On Exhaust is designed to increase power, add acceleration and throttle response, lose weight and give your machine a new deeper, throatier sound. With this exhaust, you are also eliminating the catalytic converter that is inside the OEM muffler- that means more air flow for better performance, and less heat retention for cooler engine compartment temps. You also shed a total of 14.6lbs with this exhaust on the XX.

These mufflers have a brushed stainless steel shell with a welded inlet end cap, and a steel core with packing material and a built-in spark arrestor. They are 100% rebuildable with all inner parts being removable. They come standard with a stainless steel turn down outlet end cap, but you can also choose a polished finish machined aluminum end cap or an anodized aluminum end cap in black, red, blue, gold, or green at no extra charge.

Muffler Comparison:

Stock 97dB @4500 rpm - 112dB @9000rpm - 20.8lbs with heat shields
   L2 106dB @4500 rpm - 114dB @9000 rpm - 6.2lbs installed = 14.6 lbs savings
  Q6 102dB @4500 rpm - 111dB @9000 rpm - 9.9lbs installed = 10.9 lbs savings

The difference in the dB readings at 4500 on the Stock and Q6 parts can be misleading as the sound of the Q6 is much more friendly and tolerable compared to stock. The Q6 also has a different tone compared to stock- the stock rattle / vibration sound is gone with the Q6- this does not show up on the decibel meter but anyone who is sensitive to this sound will notice the difference right away.

- Speedwerx Stainless Steel Exhaust Header- Our header features CNC machined flanges, stepped diameter equal length primary tubes, and 3-into-1 merge collector to maximize overall power and performance. All joints are hand-prepped and sand rolled prior to the purge TIG welding process, so you get great looking welds and the smoothest surface possible inside of the tubes- just like our race car headers that have won hundreds of races across the country.

- Speedwerx Hypershift Clutch Kit- The Hypershift Clutch Kit includes our Machined Weights with an Adjustment Kit, H5 Alloy Secondary Spring, and a Custom Cut Helix. These kits are designed and rigorously tested by the staff at Speedwerx to insure that it will increase your machine’s acceleration, backshift and all-around performance.

- Speedwerx High Flow Air Intake- This High Flow Air Intake offers better filtration and more flow with a larger filter than the stock setup. It bolts right into the stock location with no fabrication required.

- Dynojet Power Commander V Fuel Controller- The PCV allows us to maximize performance by tuning the fuel injection parameters to eliminate any rich or lean spots in the fuel mapping when changing the exhaust and intake. Our custom tuned map ensures maximum trouble free power using 87 Octane pump fuel. It's also easily user-tunable, so if you decide you want to upgrade other components down the road all you have to do is upload a new map in the PCV and you'll be ready to roll.

- Optional Speedwerx Q6 Stainless Steel Slip-On Muffler- The Q6 Slip-On Muffler's fully welded, baffled stainless steel design means there's no internal packing for quiet, maintenance free power. It has a different tone or pitch with only a few db increase over stock, so it's perfect for those looking for a better sounding exhaust with a more moderate sound level. It also gives you a nice 10.9lb weight loss on the XX as well. 

- Optional ECU Programming- These programs have been in the works for some time now, and we're finally ready to let the cat out of the bag! They have some cool features many have been looking for, most notably the Raised Speed and Rev Limiters in addition to the added Power and Performance without the need for a separate fuel controller. Another unique feature is the optional Multi-Map Pedal Tune that enables you to dial in the drive by wire pedal response for different riding conditions. Using the same technology as our popular and proven programs for the Arctic Cat 9000 Series Snowmobiles, we also have Flash Tools available for Dealers and Performance Shops to program machines on the spot via the factory diagnostic port so there's no risk of damage from cracking the ECU open or addtional wait time shipping. As always, any consumer or dealer can send the ECU directly to Speedwerx for programming- we typically program and ship within one business day for minimal downtime as well.

Standard Features For All Programs:

  • Reworked Fuel and Ignition Tables for Added Power and Performance using 91 Octane Pump Fuel
  • Horsepower Increased Over Stock (up to 7 whp when combined with slip-on exhaust). 
  • Rev Limiter Raised to 9800
  • Speed Limiter Raised to 120 MPH
  • Left Foot Braking enabled so you can operate the throttle and brake at the same time without going into limp mode
  • Race Start feature enables you to start in gear without pushing the brake
  • Cooling Fan Activation temps lowered 15° for a cooler running engine
  • Drive By Wire Pedal Map revised for more aggressive throttle response
  • Diagnostic Port Flash - your ECU does not have to be opened up or even removed from the machine! 

Additional Multi-Map Pedal Tune Features:

  • Dash Flash for the Digital Gauge Cluster enables Multi-Map Pedal Tunes
  • Choose between three pre-set Pedal Tunes for different riding conditions- M1 VERY aggressive (drag racing), M2 linear (duning, general trail riding) and M3 fine (rock crawling)
  • Vehicle Speed Limiter can be set via the dash. This would allow younger or less experienced drivers use the vehicle more safely. The speed limit can be pin protected for added safety!

NOTE: If you have purchased our ECU Programming and wish to make a change, Stage 1-3 programs may be changed to a different Stage 1-3 for $50, or upgraded to the Stage 3R for $100. Any Single Stage program may also be upgraded to the Multi-Map Pedal Tune version for $300. 

You must send your ECU box (and Digital Gauge Cluster if purchasing the Multi-Map) to us for programing! Please include a copy of your invoice or a note with your return address and order number. Your ECU and Gauge will typically be re-mapped and shipped within one business day for minimal downtime- the return shipping cost for the service of your choice will be added when purchasing online.
