Cobra's Speedster systems combine traditional styling and modern performance technology. These triple-chromed, shotgun-styled pipes feature full-length, 222-degree heat shields and chromed aluminum billet tips. They also deliver power gains over stock that are among the highest in the business. In part those gains come from the Cobra PowerPort, our proprietary crossover technology that helps to increase overall power from idle to redline. The end result is the Speedsters deliver the kind of power increase you normally experience with a 2-into-1 system, while retaining the clean classic lines of a 2-into-2 pipe. The system is equipped with oxygen sensor bungs so you can take advantage of your motorcycle's closed loop technology.
