Note: The 2021-2022 Yamaha Raptor has a different ECU than its older models. The ECU will not allow the factory speed sensor to be deleted. If you select 2021-2022 the exhaust system will not come with a block-off plate for the speed sensor as it will be retained. If you have a 2015-2020 and you would like to retain your factory speed sensor you may choose 2021-2022 for the year of your Raptor. Keeping your speed sensor will retard the timing in 5th gear as it came from the factory
