Built specifically for the 2011-2014 Mustang V6, the MBRP S7227409 axle-back system replaces the factory mufflers with a dual split-rear exit layout in corrosion-resistant T409 stainless steel, delivering a deeper exhaust note without the drone of a full catback swap.
T409 stainless construction throughout. T409 stainless steel resists corrosion and heat cycling over years of daily driving and weekend runs, maintaining its finish and structural integrity through freeze-thaw seasons and road salt exposure.
3-inch diameter piping. The larger 3-inch mandrel-bent tubing reduces backpressure compared to the factory system, letting exhaust gases exit more freely for improved flow through the entire rpm range.
Dual split-rear exit configuration. The split-rear exit layout routes exhaust to both sides of the rear fascia, giving the V6 Mustang a symmetrical appearance that matches the visual presence of higher-trim models. Mufflers on both sides keep the tone balanced and the sound character consistent under acceleration.
Axle-back simplicity. As an axle-back system, installation stays straightforward: remove the factory units at the axle-back connection point and bolt the MBRP system in place. No cutting, no welding, and no tuning changes are required. The system uses existing hangers and mounting locations so the job stays accessible for a home installer.
