Speedwerx Stealth Exterminator Kit

Our Exterminator Kits are designed to ensure our customers are running the correct combination of parts for their particular model. Our Exterminator Kits are designed for everyday type riding and require premium pump gas. We have grouped different options of our performance parts together to ensure our customers are looking at the correct combination of parts, giving you the confidence that you are getting the best bang for your buck.

Stealth Exterminator Kit Includes:

  • ECU Re-mapping- Stage 1 - 220+ hp 
  • Hypershift Clutch Kit
  • Aluminum Panel Vent Kit

The Stealth Exterminator Kit is for those that want increased power and performance with the stock muffler. It features our Stage 1 ECU re-mapping that gives you an 18+ hp increase. This package also comes with a Hypershift Clutch Kit to ensure you are putting the power to the ground, and our Aluminum Panel Vent kit to keep things cool underhood.

NOTE: You must send your ECU to us for re-mapping! If purchasing online, please include a note with your return address and order number. The kit will then ship the next business day after receiving your ECU. Gauge Cluster must also be sent in if you are purchasing the Multi-Map Bundle + Dash Upgrade.

Billy Howard from our Eastern Distributor Howard’s Inc. brought his machine to DynoTech Research where they ran the three maps in addition to the stock baseline and our Stage 1 muffler that does not require an ECU remap.
