Borla ATAK Axle-Back Exhaust System with Polished Tips (11827) - 2012-2014 Jeep Grand Cherokee SRT-8 6.4L V8
Unleash the highest available decibel levels and an uncompromising, track-ready roar from your high-performance SUV with the Borla ATAK Axle-Back Exhaust System. Specially custom-engineered for the 2012 to 2014 Jeep Grand Cherokee SRT-8 (WK2) equipped with the 6.4L HEMI V8, this premium performance setup is engineered for purists who want maximum volume and presence. ATAK (Acoustically-Tuned Applied Kinetics) technology is based on specifically-tuned attributes of the internal muffler cores, calibrated on a vehicle-by-vehicle basis to deliver an aggressive, rich sound profile. Even though the exterior tone is incredibly intense, the sound inside the cabin remains clean and devoid of harsh resonance, resulting from painstaking engineering and over 40 years of experience.
This high-performance axle-back system features heavy-duty 2.75 inch mandrel-bent tubing crafted entirely from aircraft-grade T-304 austenitic stainless steel. Designed to outlast lower-tier T-400 series or aluminized copies, premium T-304 construction provides ultimate protection against rust, corrosion, and cracking under extreme driving conditions. Built using precision computer numerical control (CNC) manufacturing, this kit guarantees an accurate fitment and a direct bolt-on installation using standard factory hangers. The system routes down to a commanding dual rear exit layout, crowned with massive 5 inch round, rolled, angle-cut polished stainless steel tips that completely fill out the factory bumper valance. By optimizing exhaust velocity and maximizing flow, this system uncovers hidden horsepower and torque, all backed by Borla’s legendary Million-Mile Warranty.
