Exhaust Servo Eliminator

(111 customer reviews)


All of our exhaust servo eliminators (ESE) are built using the very best engineering practices. They are built first and foremost for performance, robustness and customer satisfaction. We offer a full 10 year warranty on this product! The kit is made from one solid piece of CNC’d Delrin(R) material and potted with marine grade automotive epoxy which yields a 100% sealed enclosure against dirt, grease and moisture.

If you are keeping the stock servo motor on the bike don’t forget to add a blank mating connector with dummy rubber plugs to protect the open floating connector dry and dirt/rust free.  *If you are getting an error code that cannot be cleared with the stock hardware. Please do NOT order this item. It will not fix the issue.

Our Exhaust Servo Eliminators/Emulators (ESE) are digitally controlled via a microprocessor and onboard voltage regulator that guarantees not to lose servo position during whatever extreme conditions; Unlike other products that are purely analog.  Manufactured in-house in the USA.

This kit allows for the replacement of the servo actuator assembly as factory installed on all new motorcycles as part of the exhaust system integrated with the ECU (Electronic Control Unit). The unit gets rid of the servo setup thus giving your bike a cleaner look, leaving more room under the seat, saves weight, improves performance and sound. A lot cheaper than a full system aftermarket setup to simply clear any CEL/FI/EXEC error codes!

*If you are getting an error code that cannot be cleared with the stock hardware. Please do NOT order this item. It will not fix the issue. Contact us for more details.

Device is for off-highway or showroom use only.

Simple installation
1. Unplug and remove the factory exhaust valve actuator.
2. Remove cable(s) to the actual valve installed within the exhaust. The valve will default to the open position. Verify before proceeding.
3. Plug the ESE into the factory wiring harness using the stock connector to secure. Use the optional blank connector with dummy rubber seals to cap off the unused connector on motor side.
4. Turn on your ignition and verify your Check Engine Light (CEL) message is off.

Your motorcycle’s ECU will never know if it is talking to the stock servo motor assembly or if it is talking to our 0.7oz (20 grams) eliminator!

    Hi. I bought the Vizi-tec exhaust valve delete plug in dongle for my 2018 Suzuki DL1000XT to eliminate the check engine code/light after installing a Delkevic cat delete system. I completely removed the stock catalytic converter/butterfly valve/silencer assembly and bolted on the Delkevic mid pipe & silencer. I then started the bike and immediately got a check engine light contrary to what delkevic states on their description for their exhaust product. Delkevic states no tuning necessary when using their exhaust. I contacted Delkevic and asked them why am I getting a check engine light to which the tech replied you need an exhaust valve delete dongle. So I did my research and found a few products and decided I would take a chance on the Vizi-tec at the lowest price point of $40 bucks and I am happy to say it works perfectly! The bike runs great and sounds great. Don’t spend $300 to $400 on a power commander as the stock tune works fine. I don’t know why Delkevic doesn’t partner with Vizi-tech and include the dongle with their system because they would have much happier customers if they included it with their cat delete systems. So cudos to Vizi-tec! The item arrived promptly and customer service contacted me more than once to make sure I am happy! Who does that anymore!!!? Not Delkevic….although I am happy with their pipe/value after all is said and done.. Cheers from Cali,

    I purchased the DUC-EE for my 2019 Multistrada 950S. The install was super easy and no codes. When I had a couple questions Bernard responded in less than a few hours! I’ll definitely be buying my brake modulator from Bernard when I’m ready. Excellent customer service!!
