Product Description

The CORSA Performance 14316 Sport Axle-Back Exhaust is designed specifically for 2011-2014 Ford Mustang GT and 2011-2013 Boss 302 models powered by the 5.0L V8. Constructed from premium 304 stainless steel with 3.0" mandrel-bent piping, this system significantly enhances exhaust flow - roughly 150% more than stock - while shedding around 18 lb from the rear of the vehicle.

Featuring CORSA's patented Reflective Sound Cancellation® (RSC) technology, the 14316 offers an aggressive, sporty exhaust note under acceleration without any annoying cabin drone at cruising speeds. With gains of approximately +7 horsepower and +4 lb-ft torque, this bolt-on exhaust delivers real-world performance in a direct-fit package - no welding, cutting, or modifications required.

Backed by a limited lifetime warranty and proudly made in the USA, the CORSA 14316 is the ideal upgrade for Mustang enthusiasts seeking bold sound, enhanced response, and lightweight performance. Fitment confirmed through 2014; 2015-2025 coverage remains unconfirmed and not recommended for non-V8 or AWD variants.
