- Frequently asked questions.My original exhaust has an EXUP Valve, yours does not have the valve will it lose performance ?There will be no power loss, by using the latest exhaust design the Exup valve is no longer a requirement.My friend removed his Exup valve from the original headers and it now performs badly.Yes, this is correct, the original headers use a large cast iron chamber, the original can not be converted to work without the valve, removing the valve from the original headers will cause power loss. When the original Exup valve is fixed in place there is a power loss as certain RPM. Will yours have the same problems.The original valve will cause problems when secured in only one position, the chamber and valve for the Exup does not allow for it to be in a permanently fixed position.My EXUP valve has a servo motor connected to it, will it give a fault code if I remove it?We recommend leaving the exhaust servo motor in place, by only removing the drive cables no fault code will appear. If the servo motor is unplugged from the wiring loom a fault code will show on the rev counter on start up. Servo buddies can be used if you wish to remove the servo and do not want a fault code to display.I have a silencer/muffler that fits the original bolt type flange will it also fit yours?Yes, any silencer/muffler that fits the original Yamaha headers will also fit ours. We use the same exact style connection with the same bolt on fitment.
