Description

Exhaust Servo Eliminator (ESE)

Built-in microprocessor ensures optimal function and offers great compatibility. Just plug it in and enjoy the ride!

The unit itself is almost smaller than the OEM connector it connects to.

Works with all aftermarket slip-ons, full systems, and even with the stock exhaust.

OEM exhaust cans and systems won’t win a beauty contest these days (and rarely did they in the past). They weigh a lot more than aftermarket counterparts, sound poor, and rarely allow you to reach your bike’s full potential. Whatever your reason to change your end-can or whole system, removing the exhaust valve will leave you with the dreaded FI light. Install the ESE to take care of that so that the FI light will only come on when there’s an actual trouble with the engine.

Features

• Regain useful space while shedding weight: This tiny little fella will eliminate the bulky, heavy, and space-wasting OEM servo motor with the operating cables and wiring, saving up to 1 kg and freeing up a lot of under-seat storage. Also, you may now get rid of the exhaust valve too by replacing the exhaust system.
• Awesome Tech: Built-in microprocessor ensures optimal function and great compatibility. If your bike is equipped with an exhaust servo, you’ll need an ESE module — whether you replace the exhaust system or add a fuel controller module (or both).
• Plug ‘n Go install: All ESE models are Plug ‘n Go, and installation is a breeze. Just locate the exhaust servo motor under the rider/passenger seat, disconnect the plugs, plug in the ESE to the OEM connector, and that’s it — you’re ready for the ride!

What is an Exhaust Servo Valve?

For the last two decades, bikes have been equipped with an exhaust flap valve (also called the EXUP valve) to improve low-end torque by hindering the flow of escaping gases, creating back pressure in the exhaust system. As the revs rise and you open the throttle more, this valve opens progressively so gases can exit unblocked.

This valve and its housing are welded after the header’s downpipes, right before the collector pipe and/or the collector chamber/catalytic converter. Removing this valve alone from the factory system is usually not worth the time, money, or effort since the OEM system in most cases is low quality and heavy.

Of course, titanium OEM systems exist, but finding an exhaust shop with titanium welding capabilities isn’t easy and will cost you an arm and a leg in labor to remove the exhaust valve from the system. So it’s easier and yields better results to opt for an aftermarket end-can or whole system. Either way, you’ll need an Exhaust Servo Eliminator to complete the job properly!
