Gibson Performance Mufflers
Gibson Superflow™ Mufflers exceed the performance advantages provided by all other mufflers on the market. They are the industry's most reliable and trouble-free performance muffler available. Why settle for noise when you can have MORE POWER and TORQUE. The Gibson difference is that our mufflers deliver the powerful "big block" sound at the tailpipe and are quiter inside the cab than any other aftermarket mufflers.
