Description
Built around the fitment needs of the 2013-2014 Mustang GT / Boss 302 5.0L V8 Single Split Rr Exit (Rear Section), this Borla offering targets the part of the driving experience the factory exhaust often leaves understated: sound and personality. The role of this axle-back exhaust system is straightforward: it changes the rear muffler and outlet section, giving the car a more purposeful voice and appearance without replacing as much of the factory exhaust.
It makes particular sense for an owner who wants a meaningful change at the rear of the car while keeping more of the original exhaust system in place than a full cat-back replacement would. In practice, this product is best suited to enthusiasts who want a stronger muscle-car soundtrack and a more assertive rear-end presence for spirited street use, meets, and occasional track work.

About Borla
A long-established name in performance exhaust, Borla focuses on engineered sound as much as hardware—developing systems around individual vehicle applications rather than relying on a universal approach. That background makes this product a natural choice for a build where exhaust tone and fitment matter as much as simply replacing factory hardware.
Fitment note: Confirm model year, engine, trim, factory exhaust equipment, and the selected Borla part number before ordering.
