Nothing is simpler than a drag pipe. What's not to understand? The straightest possible pipe, the fewest possible bends, the least possible backpressure. 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's 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. Uses stock front headers.
