Since fitting the ESE, the red light has gone out on the dash, the bike sounds better and seem to make better power lower in the rev range.
The exhaust valve on my Aprilia had become faulty. The engine red light was lit on the dash.
By using the Healtech ESE, I was able to lock the exhaust valve in the open position and remove the servo motor and cables.
The Healtech ESE came with good instructions and further information is available on their website.
After removing the servo motor, it was simple plug and play.

I'm very happy with it.
