Stage 2 Exterminator Kit // 2013-2019 Wildcat X / 4X

Speedwerx Stage 2 Exterminator Kit // 2013-2019 Arctic Cat Wildcat X / 4X

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 2013-2019 Arctic Cat Wildcat X or 4X comes with our Speedwerx L2 Stainless Steel Slip-On Exhaust, Stainless Steel Exhaust Header, Hypershift Clutch Kit and a Dynojet Power Commander 6 Fuel Controller.

Speedwerx L2 Stainless Steel Slip-On Muffler- This 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.

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, but aluminum endcaps with a natural finish or anodized black, red, blue, gold, or green are available as an upgrade as well. These are assembled as ordered due to these options, so please allow 2-3 business days before shipment. 

The stock muffler weighs in at over 16lbs, and the L2 comes in at just 5.5lbs- that's a weight loss of over 10.5lbs!

Speedwerx Stainless Steel Exhaust Header- Our header features CNC machined flanges, stepped diameter equal length primary tubes, and 2-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. Note- 2013-2014 models with the dual inlet muffler are converted to the 2015-2018 style single inlet with this kit, and an O2 sensor bung plug, the exhaust donut gasket and an updated coolant hose needed to retrofit this style exhaust are included when orderering the kit for a 2013-2014 model.

Speedwerx Hypershift Clutch Kit- Our Hypershift Clutch Kit includes our 6-Series Machined Weights with an Adjustment Kit. The kits for 4X models also include new Primary and Secondary Springs. These kits were designed and rigorously tested by the staff at Speedwerx to insure that it will increase your machine’s acceleration, backshift and all-around performance.

NOTE: For 4X models only- you must verify the part number shown on the green tag on your primary clutch before ordering- the springs are different between the 0823-386 and 0823-498 clutches!

Dynojet Power Commander 6 Fuel Controller-  The PC6 allows us to maximize performance by tuning the fuel injection parameters. Our custom tuned map ensures maximum trouble free power using 91+ Octane premium 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 PC6 and you'll be ready to roll.

Options: Q6 Muffler, Copper Exhaust Gaskets, O2 Sensor Bungs

Q6 Muffler: We can substitute the Q6 Quiet Muffler for the L2 Muffler. This muffler is designed to increase power, add acceleration and throttle response, lose weight, and be maintenance free all while being only slightly louder than stock. It's full stainless steel construction with no internal packing means it's built to last, and the built-in spark arrestor and a low decibel rating (94-95 dB vs stock at 90-91dB) means it's very trail-friendly too. 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. All Q6 mufflers now come standard with turndown outlets to clear accessory bumpers.

Heavy Duty Copper Exhaust Gaskets: These are highly recommended as stock gaskets start to block the exhaust port as they wear, significantly reducing performance over time.

O2 Sensor Bung: A single bung for the OEM O2 sensor is standard on all headers, but you can order one or two additional bungs for a Dynojet Autotune or an aftermarket AFR gauge.
