The Twist Dynamics WP Dual is the best sounding, hottest looking exhaust system offered for the Polaris Slingshot. Can be purchased in CAT back or CAT delete and is our most popular, best selling exhaust system. If you have plans to go boosted in the future, please contact us prior to ordering this system. As with all WP products, all routing is ABOVE the frame rail which equates to zero loss of ground clearance on an already low profile vehicle. Offered in a flat black or Carbon Fiber.
