Gibson exhaust systems are engineered to not only produce an optimum increase throughout the power band but provide a deep powerful exhaust tone when you put the pedal to the metal! These systems are engineered using the proven GIBSON Superflow Muffler CFT design- Convergent Flow Technology, features a unique internal chambered and louvered design that creates a venture effect. Exhaust gases converge to equalize and synchronize exhaust pulses while chambers create pressure to actually “PULL” exhaust gases out at an increased velocity. Directional louvered tuning ports guide exhaust gases into resonance chambers to create a deep powerful exhaust tone. This proven technology is responsible for maximizing exhaust flow, a powerful sounding exhaust tone
