    Better Performance. The straight-through muffler design of this MWA Center Oval Muffler produces enhanced volume with unrestricted flow. Typically, stock mufflers have 34% or more exhaust restriction and other aftermarket mufflers have over 20% restriction. Gibson Superflow Mufflers only have about a 5% restriction. This is because Gibson custom power-tunes their mufflers.

    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.

    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 1997-2017 Jeep Wrangler TJ and JK equipped with a 2.25" inlet and outlet. Sold individually.
