Speedwerx Stage 1 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 1 Exterminator Kit for the 2018 Wildcat XX comes with our Speedwerx L2 Series Stainless Steel Slip-On Exhaust, Hypershift Clutch Kit, 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. (Q6 availability TBA) With this kit, you can easily upgrade to the Stage 2 spec down the road by adding our Stainless Steel Exhaust Header and High Flow Air Intake.


- 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.

- 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.

- 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 is only 2-3db louder than stock and the fully welded, baffled stainless steel design means there's no internal packing for quiet, maintenance free power. It also gives you a nice 10.3lb weight loss on the XX as well.
