Take control of your vehicle’s sound and performance with the M.Flow xMOD Universal Muffler. Part of the modular xMOD Series, this innovative muffler lets you easily switch between three unique sound profiles—giving you the power to customize your exhaust note for street, sport, or track.
Crafted from premium 304 stainless steel, the #14006 features a 5” x 8” x 18” muffler body with 2.5” inlet and outlet diameters, built to deliver dyno-proven performance and long-lasting durability.
The xMOD Universal Muffler includes three interchangeable configurations:
NDT Module – Integrates a quarter-wave resonator to minimize cabin drone using M.Flow’s No Drone Technology.
Muffler Module – Uses a block-off cap to close the additional port and produce M.Flow’s signature deep, smooth tone.
xTreme Bypass Module – Opens the system fully for a straight-pipe effect and maximum sound output (for track/off-road use only).
Changing configurations is simple—just use the included band clamp to swap modules at the secondary port near the exhaust outlet. All options are engineered for consistent flow and performance, with the only difference being the tone.
