SFT Superflow Muffler

Why settle for noise when you can have MORE POWER and TORQUE with Gibson Superflow Round Mufflers. Gibson mufflers deliver the powerful “big block” sound at the tailpipe with more usable pulling power and torque! The Gibson difference is that our mufflers are quieter inside the cab than any other aftermarket mufflers.
