is inspired and designed from GT racing in Japan. M7 has incorporated this new race inspired offset muffler and piping design into applications, which offer a greater flow and higher-RPM power gains due to the less restrictive design. Increasing the amount of exhaust flow is the first step to increased engine performance and efficiency. The factory or standard exhaust system represents a restriction in the stock configuration. By designing a system that increases the mass and velocity of exhaust flow, it allows for a reduction in back pressure and thermal stress, thus unleashing the engine's potential for increased power, torque and responsiveness. This JASMA approved muffler came with adjustable tip and removable silencer.
