Cobra's Speedster systems combine traditional styling and modern performance technology

These shotgun pipes also produce class-leading power gains

In part, the power gains come from the Cobra PowerPort, their proprietary crossover technology that helps to increase overall power from idle to redline

Delivers the kind of power increase you normally experience with a 2:1 system, while retaining the clean classic lines of a 2:2 pipe

Full-length, 222° heat shields

IMPORTANT: On 2021-up UK, EU and international models Harley introduced additional O2 sensors located towards the end of the mufflers. These additional O2 sensors need to be eliminated using the Vance & Hines FP4 Fuelpak (Part # 66043) and blanking plugs (Part # 744444) on our website. Alternatively, you can contact your local HD dealership for advice on this issue as they may be able to eliminate the O2 sensors for you
