Speedwerx Stage 2 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.

Stage 2 Exterminator Kit Includes:

  • L2 Stainless Steel Stage 2 Lightweight Muffler
  • Hypershift Clutch Kit
  • Panel Vent Kit
  • Aluminum Charge Tube Kit
  • ECU Re-mapping- Stage 2 - 250+ hp (Stage 3 - 270+ hp, or the Multi-Map Bundle + Dash Upgrade are optional)

The Stage 2 Exterminator Kit is for those that want a basic bolt-on package with the increased power and performance that is only possible with a re-mapped ECU. It features our TIG welded 304 Stainless Steel Stage 2 Lightweight Muffler- after extensive testing, we saw a solid 23hp gain over stock with no mapping or fuel changes, however it bumps up the boost slightly and leans out the air-fuel ratio so our ECU remapping is required to ensure long term reliabilityThe Stage 2 muffler combined with the Stage 2 ECU re-mapping gets you over 250hp, and you also have the option to select the Stage 3 re-mapping for 270hp plus, or choose the Multi-Map Bundle + Dash Upgrade to get a selectable, fully adjustable setup right in your stock gauge cluster- see related items below for more details. This package also comes with a Hypershift Clutch Kit to ensure you are putting the power to the ground, an Aluminum Panel Vent kit to keep things cool underhood, and our Aluminum Charge Tube Kit to replace the stock rubber hoses that tend to stretch and get weaker over time. The aluminum tubes also have the added bonus of greater heat dissapation since they are exposed to the cold air, and a cooler intake charge equals more power!

Those of you with Yamaha Sidewinders can also select the option to delete the clutch kit. 

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.
