Loud, Aggressive Sound. Want to ensure every head it turned as you drive by in your Shelby GT500? Add a touch of Borla excellence to your 2011-2012 5.4L Shelby GT500 with this ATAK Cat-Back Exhaust System to obtain an extremely aggressive muscle car sound that is not for the faint of heart.

ATAK. Acoustically-Tuned Applied Kinetics, also known as "ATAK," is Borla's newest technology that produces the highest available dB (decibel) levels to pump the volume, while retaining clarity of sound and avoiding distortion that's typically found in louder exhausts.

High Quality Construction. Manufactured from ultra smooth, mandrel-bent 2.75" stainless steel tubing to improve exhaust flow, this Borla Cat-Back Exhaust features over-axle pipes and (2) exclusive ATAK race inspired mufflers with two stainless steel 4.5" round slant tips that have been embossed with the Borla Logo. All necessary hardware is included for a complete installation.

Direct Bolt-On Installation. Engineered to be a direct upgrade replacement for your 5.4L GT500's factory exhaust, the Borla ATAK Cat-Back Exhaust easily bolts up in the stock location with no modifications required.

Application. This Borla ATAK Cat-Back Exhaust System is specifically designed for use on 2011-2012 Shelby GT500 Mustangs equipped with a manual transmission and either aftermarket shorty headers or the factory manifolds.
