The Mishimoto Race Series axle-back deletes the muffler for the raw sound of the Mustang GT's 5.0L Coyote V8 under acceleration. It is built from mandrel-bent 304 stainless steel for smooth flow and runs dual 4.5 inch double-wall polished tips, fits both manual and automatic cars, and installs with a cut-and-clamp design. It sits downstream of the rear axle and does not interact with emissions components. Backed by the Mishimoto Lifetime Warranty.
