Gibson 55121S - Gibson Superflow Mufflers

The Superflow Difference

The Gibson Superflow Muffler is an exhaust system capable of not only delivering optimum performance and powerful sound, but a system that continues to produce expected results after miles on the road. Many muffler products on the market today are manufactured utilizing packing material or thin baffles placed inside the muffler casing. While some of these mufflers sound good when new, after moderate use packing begins to loose density and baffles become brittle. Over time as these internal elements disintegrate increased resonance may be heard inside the vehicle and a weakened exhaust sound heard on the street. Made in the U.S.A.

Convergent Flow Technology - CFT

Gibson Convergent Flow Technology utilizes a design based on a solid internal angular induction chamber that pressurizes the flow of exhaust at the entry point before pushing it through a series of integrated tuning ports. This ''Push Through'' engineering creates a rapid venturi vacuum effect on the converging flow of gases efficiently producing more power than a regular pull through muffler design. Gibson CFT Technology is proven to not only optimize exhaust flow but increase horsepower, increase fuel efficiency and provide a unique and powerful sounding exhaust tone for today's cars and trucks.

Whether on or off road, the unique convergent flow design and solid construction of the Gibson system delivers more for your money when compared to other mufflers on the market.

Tuned By Gibson

Pure sounding exhaust tone comes only from a quality engineered internal design. The Angular Induction system engineered into the Superflow muffler is the key to the unique Gibson sound and the foundation of our Convergent Flow Technology. A series of integrated Tuning Ports are stamped evenly on all sides of the chamber during manufacturing. These ports act as tuning instruments filtering unwanted noise as the high velocity gas flows through the angled convergent chamber. The end result is emission of pure sound and the deep exhaust tone Gibson systems are known for.
