Our stainless steel D-Plate is a low cost alternative for replacing the catalytic converter in the GP1200R, GP1300R , XL1200, and XLT1200LTD. It is a duplicate of the plate Yamaha used in countries that did not require a catalytic converter. Removal of the catalytic converter reduces engine bay temperatures, increases power, and gives you the freedom to use regular 2-stroke oil. Due to it’s effects on passing emissions tests, it is intended forĀ competition use only.

If installing on Catalytic Converter equipped models with OEM CDI we recommend our Cat Temp Sensor Chip. The circuit is designed to mimic the signal sent to the OEM CDI by the catalytic converter’s temperature probe preventing CDI flutters, warning devices sounding and engine shut downs due to cat removal.
