Overview

The Speedwerx Stage 2 Exterminator Kit is a comprehensive bolt-on performance package designed for the Arctic Cat 800 C-TEC2 engine. This kit aims to maximize power and performance for everyday riding, requiring premium pump gas. It includes a Speedwerx Fat Daddy Single Pipe and Ceramic Coated Y-Pipe, an ECU Reflash, Stealth Head Mod, Hypershift Clutch Kit, VForce3R Carbon Reed Valves, Frogzskin High Flow Intake Vents, a Speedwerx Aluminum Panel Vent Kit, and an Exhaust Valve Cable Gauge.

On the dyno, this kit achieved a peak of 164.3hp and 103.9 ft-lbs of torque, representing an increase of 12.3hp and 6.5 ft-lbs over stock. This performance improvement offers higher RPM capability and better over-rev power, making it more forgiving on clutch setups and enhancing top-end performance for challenging terrain. The kit also contributes to significant weight savings, with the pipe and Y-pipe assembly being 4.5lbs lighter than stock, and a total potential weight loss of up to 18lbs when combined with a lightweight muffler.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
