Gibson Superflow Round Body Mufflers

The Gibson Difference

Gibson Universal Performance Muffler delivers 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 muffler. Featuring a baffled and chambered Muffler (not packed or screened, nothing to blow out) for better volume efficiency with unrestricted flow. All welded construction. Straight-through design for maximum flow. Backed by a Lifetime Limited Warranty.
