Description
More Power. The Borla ATAK Split Side Exit Cat-Back Exhaust is a great way to improve the horsepower and torque of your 2014-2018 5.3L GMC Sierra. You’ll see improvements in both performance and fuel economy as well as get that aggressive, throaty Borla roar.
ATAK. Acoustically-Tuned Applied Kinetics, is Borla’s newest technology that produces the highest available dB (decibel) levels to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts. The ATAK muffler uses a multi-core straight-through design with both perforated stainless cores and ceramic material to absorb high-pitched sounds.
High Quality Construction. Manufactured from ultra smooth mandrel bent T-304 stainless steel tubing to improve exhaust flow, this Borla catback exhaust system steps down from a 2.75-inch inlet to dual 2.25 outlets. The two included race inspired “ATAK” mufflers feature 4″ chromed stainless steel tips that are embossed with the Borla logo for both impressive looks and great sound.
Installation. Verify that all parts of the kit are present prior to beginning installation. Once complete, follow all instructions carefully. Check your exhaust system after the first few hundred miles and re-tighten any clamps that need tightening.
