SpeedWerx 2016-2019 Arctic Cat Wildcat Sport Stage 1 Exterminator Kit
The Speedwerx Stage 1 Exterminator Kit for the Arctic Cat Wildcat Sport is a complete performance upgrade designed to deliver noticeable improvements in acceleration, throttle response, and top-end speed while remaining cost-effective.
The kit includes the Speedwerx L2 Stainless Steel Slip-On Muffler, which not only sheds over 11 pounds compared to the stock muffler but also eliminates the OEM catalytic converter to improve airflow and reduce engine heat. Its stainless steel construction, rebuildable internals, and spark arrestor make it both durable and practical, while the available anodized end caps or stainless steel turndown options allow for customization.
The package also features the Speedwerx Hypershift Clutch Kit, which includes precision-machined weights, a primary spring, and an H5 Alloy secondary spring to optimize acceleration, backshifting, and overall drivability. Completing the kit is the Dynojet Power Commander 6, which tunes fuel injection and ignition timing, raises the rev limiter to 8,500 RPM, and provides a custom map for 91+ octane fuel. Optional upgrades include a secondary spring delete or the Q6 muffler, a trail-friendly, maintenance-free alternative to the L2.
Overall, this kit offers a balanced combination of power, efficiency, and reliability, with easy pathways for future upgrades to Stage 2 performance.
