    Optimum Performance. Crafted from stainless steel, this Superflow Muffler from Gibson utilizes a non-directional, straight-thru design, a system that pushes exhaust at rates just 3cfm under a typical 3-in. straight pipe. The Gibson MWA 3" Superflow Muffler is designed to give you better performance potential while keeping the noise inside the car to a minimum.

    Quality Construction. No thin baffles or packing materials are used in the manufacturing of this Superflow Muffler. With a 3" center inlet and 3" dual outlet, this muffler eliminates two problems that commonly leads to increased cab noise and weakened exhaust tone, those being brittle baffles and deteriorating packing. The result is a tone that stays deep and resonates throughout the life of the muffler. Plus, the omission of internal packing means a lighter weight design.

    Lifetime Warranty. Gibson backs their Superflow mufflers with a Limited Lifetime Warranty for craftsmanship. Some exclusions apply, see the Gibson site for details.

    Application. The Gibson 3 in. Stainless MWA Superflow Center/Dual Oval Muffler is designed for any 1997-2017 Jeep Wrangler TJ and JK equipped with a 3" inlet and outlet. Sold individually.
