Superflow Mufflers
Gibson Superflow Mufflers exceed the performance advantages provided by all other mufflers on the market. They are the industry’s most cost-effective, reliable, and trouble-free performance muffler you can purchase. Why settle for noise when you can have MORE POWER and TORQUE with a Gibson Superflow Muffler.

Gibson delivers the powerful “big block” sound at the tailpipe…the Gibson difference is that our mufflers are quieter in the cab than other aftermarket mufflers, with more useable pulling power and torque! By baffling & chambering our Superflow Mufflers, (not packed or screened, nothing to blow out) we promote better volume efficiency. Plus, the added thickness of our case, and the thicker gauge tubing, all contribute to keeping the noise inside the system and releasing it where you should hear it... not in the vehicle!




GIBSON SUPERFLOW MUFFLERS utilize a superior design of chambers, baffles, and louvers to provide the optimum amount of flow to increase and maximize the low-end torque powerband for people serious about towing and hauling (low to mid range torque increase). Not to mention, this is also the ideal muffler to compliment the performance characteristics of your vehicle for performance oriented daily driving (increased H.P. and increased fuel economy).
