Get that Loud Purr. With the Gibson MWA Superflow Muffler, you get maximum sound without drowning out your interior. Known for its aggressive sound, this muffler brings you a loud purr with minimum interior drone.

Performance. Straight through design for better volume efficiency with unrestricted flow. Typical factory mufflers have a 34% (or more) exhaust restriction. Aftermarket mufflers have over 20% restriction. While Gibson Superflow mufflers only have about a 5% restriction, this because Gibson custom power-tunes their mufflers. Keeping the opening diameter of the pipe constant by "mandrel bending", even through the bends, allows the exhaust pulse to flow smoothly without power robbing restrictions or backup.

Impressive Acoustics, Easy Installation. With a 2.25" center inlet and a 2.25" center outlet, this MWA Superflow Muffler produces a notable audible increase over stock mufflers, yet minimizes drone and sound transfer to the vehicle cabin. Designed to comply with sound and emission regulations, this muffler is safe to install without worrying about the boys and girls in blue.

Warranty. Gibson provides a Limited Lifetime Warranty for this MWA Muffler.

Application. This Gibson 2.25 in. Stainless MWA Superflow Center/Center Oval Muffler is designed for any 1979-2004 Mustang, excluding 1999-2004 Cobras, equipped with a 2.25" inlet and outlet. Sold individually.
