Gibson MWA Stainless Steel Muffler 2.25" Offset / 2.25" Center 14" Oval Body BM0100

Maximum Sound. Maximum Flow. Period.

The Gibson MWA Muffler is built for performance junkies who want it loud, proud, and powerful. Featuring a straight-through design, it delivers near-unrestricted flow—just 3 CFM less than a full 3-inch straight pipe. That means more power potential with less interior drone.

No packing. No baffles. No compromises. The MWA’s innovative construction eliminates restrictive internals, keeping it lightweight while producing a deep, aggressive tone that stands out from the crowd.

Crafted from high-quality stainless steel and 100% Made in the USA, this muffler is built to last—and built to perform.

Whether it’s your hot rod, daily driver, off-road beast, or weekend warrior, give it the sound and performance it deserves.
