High performance vehicles need to be in peak tune to deliver optimum power to the pavement. Gibsons CFT Superflow muffler with Convergent Flow Technology actually tunes your exhaust by using resonance chambers, directional louvered tuning ports and angular induction to draw exhaust gases into the muffler and expel it at a higher velocity. The result is a muffler that doesnt have packing to wear out, yet delivers more power and a performance sound.
