The MagnaFlow Street Series Axle-Back Performance Exhaust System 15889 enhances both sound and dyno-proven performance on your 2005–2009 Ford Mustang 4.0L. It delivers MagnaFlow’s deep, resonant signature exhaust note while maintaining moderate exterior sound levels and a mild interior tone, making it ideal for both daily driving and spirited cruising.
Constructed from durable, corrosion-resistant stainless steel, this exhaust system is built to withstand the demands of the road. The axle-back layout replaces the factory exhaust components from near the rear axle on back.
Featuring fast-flowing 2.5-inch mandrel-bent main piping and one straight-through muffler, the system terminates in a single straight passenger-side rear exit with a 3.5-inch polished welded-on double-wall angle-cut folded-edge tip, giving your Mustang a bold and aggressive look to match its sound.
Extensive 3D scanning during development ensures a precise direct-fit, bolt-on installation that can easily be completed at home. Exhaust system 15889 is manufactured using advanced CNC precision robotic techniques and is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
