Empire Industries Carbon Fiber Series Dual Exhaust for 2015+ Yamaha Raptor 700 Tig welded 304 stainless steel construction. 6061 Aluminum silencer with billet end caps makes for easy repacking. Billet silencer end caps are available in anodized, blue, black, orange, and raw. Huge 7+ Horsepower gains! 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. If you have any questions feel free to email us in the contact section or give us a call.
