Gibson Superflow Mufflers
Gibson Superflow mufflers exceed the performance advantages provided by most other mufflers on the market. With their straight-through design, they're quieter in the cab, while still delivering that "big block" sound at the tailpipe. These exhausts are cost-effective, reliable, and provide more useable pulling power and torque. Superflow mufflers are available in steel and stainless steel—in a variety of shapes, and inlet/outlet diameters and quantities for universal and vehicle-specific applications.
