Pure drag pipes work great on dragsters because they spend 100 percent of their time at full throttle. In the real world, you need a little added finesse--the Cobra touch. Cobra drag pipes have the pure, simple lines riders want, and they come with their removable power cores. With the cores in you get a great, sharp bark of an exhaust note that's still appropriate for riding in town. And you'll also get a real performance increase you can feel.
