Combines the PowerPort Duals head pipe design and the famous Cobra Speedster blueprint for a sleek dual style with an extra kick. Performs like a true 2-into-1 pipe with the clean look of a traditional dual system. Broadens the low end and mid-range torque curve, perfect for touring and highway use, and they provide a noticeable power boost across entire rpm range. Full length, 2.5-inch, single heat shields give a full seamless appearance. They give great sound that’s enhanced by the proprietary PowerPort crossover.
