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 Arctic Cat Wildcat Trail and Sport comes with our Speedwerx L2 Stainless Steel Slip-On Exhaust, Hypershift Clutch Kit and a Dynojet Power Commander V Fuel and Ignition 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 polished finish aluminum end cap, but you can also choose an anodized aluminum end cap in black, red, blue, gold, or green or a stainless steel turn down at no extra charge.

This muffler adds 5hp and sheds some weight as well- the stock muffler weighs in at 11lbs, and the L2 comes in at half that at just 5.5lbs!

Speedwerx Hypershift Clutch Kit- Our Hypershift Clutch Kit includes our 6-Series Machined Weights with an Adjustment Kit, a new Primary Spring, and a complete Secondary Clutch assembly with a multi-angle helix and our H5 Alloy Secondary Spring. This kit was 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 and Ignition Controller-  The PCV allows us to maximize performance by tuning the fuel injection and ignition timing parameters, as well as re-setting the rev limiter to a safe and reliable 8500 RPM which will give you more top end speed compared to the stock 7750 rpm rev limit. Our custom tuned map ensures maximum trouble free power using 91+ Octane premium pump fuel.

Options: Secondary Spring Delete, Q6 Muffler

Secondary Spring Delete: If you already have one of our H5 Alloy Secondary Springs, you can choose to delete it from the kit.

Q6 Muffler: We can substitute the Q6 Muffler for the L2 Stainless Steel 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. Update: All Q6 mufflers now come standard with turndown outlets to clear accessory bumpers.

Dyno Testing Info:

The dyno sheet shows a stock 14-15 Trail/Sport with only a K&N drop-in filter vs. the same with our Q6 Stainless Steel and L2 Aluminum Body Slip-On Mufflers paired with the new Dynojet Power Commander V Fuel and Ignition Controller. The Slip-Ons and PCV combo showed nice gains through the entire powerband, with the L2 at +5 hp and the Q6 at +4.5 hp over stock. As you can see, the Q6 runs nearly identical to the L2, which is pretty impressive for a muffler that is only 3-5db above stock- that should make it a great option for anyone that wants a quiet, good looking, maintenance free exhaust! The L2 is the choice for those that want a more agressive race sound and the lightest weight possible. For even more power, take a look at the Stage 2 Exterminator Kit with our new Exhaust Header that's based off the 2016 Sport with the larger muffler inlet- you can bolt on an impressive 9.5-10hp over stock on 14-17 Trail and 15 Sport models with our Header/Slip-On/PCV combo!
