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.

- 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 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.
