Our JSP Brand Aftermarket Yamaha Catalytic D-Plate and Cat Removal Chip / Temperature Sensor By-Pass Chip is compatible with the Yamaha models listed below. This plate 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 its effects on passing emissions tests, it is intended for competition use only. The Cat Removal Chip is recommended if installing on Catalytic Converter equipped with OEM CDI. 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 shutdowns due to cat removal.
