    Supreme Sound. Designed to deliver a great sounding, better performance muffler, this Gibson MWA Muffler will give your Wrangler a richer sound over factory. This MWA Superflow 3" Center/2.5" Dual Oval Muffler is designed with Gibson's straight-thru non-directional style, engineering that channels exhaust at only 3 cfm below a standard 3-in. straight pipe.

    Quality Construction. No thin baffles or packing materials are used in the manufacturing of the Superflow Muffler. With a 3" center inlet and 2.5" dual outlet, this muffler eliminates two problems that commonly lead to increased cab noise and weakened exhaust tone, those being brittle baffles and deteriorating packing. The result is a tone that stays deep and resonant 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 Stainless MWA Superflow 3" Center/2.5" Dual Outlet Oval Muffler is designed for any 1997-2017 Jeep Wrangler TJ and JK equipped with a 3" inlet. Sold individually.

      This muffler helped with the sound of exhaust specifically the deep sound. Sounds great with no rasp, deep growl, cant complain.
