Product Description

The Borla 140549 ATAK Cat-Back Exhaust System delivers the most aggressive exhaust note in Borla's street-legal lineup for the 2014-2019 Chevrolet Silverado and GMC Sierra 1500 with 5.3L V8 engine. The ATAK (Acoustically Tuned Applied Kinetics) technology produces the highest decibel levels while maintaining exceptional sound quality through vehicle-specific acoustic tuning of the patented multi-core muffler internals. Premium T-304 austenitic stainless steel construction provides superior corrosion resistance and durability compared to inferior 409 stainless systems. Mandrel-bent tubing maintains consistent pipe diameter through each bend for unrestricted exhaust flow, reducing backpressure and helping release hidden horsepower and torque. The dual split side exit design routes through polished 4" bright chrome tips for an aggressive appearance. Precision CNC manufacturing ensures bolt-on installation with no cutting or modifications. Backed by Borla's industry-leading Million-Mile Warranty for confidence on the street or trail.
