Description
High Flow System. Powering up your 2014-2018 5.3L Chevy Silverado’s engine with an extra +7-10% horsepower and torque, the Borla ATAK Split Side Exit Cat-Back Exhaust with Black Tips also gives your pickup a fierce new exhaust note. The high flow through the mandrel-bent tubing and wide open ATAK muffler – whose design produces faster exhaust venting than a similar length of straight pipe – frees the engine of fume backpressure and improves combustion and thus power. Gas mileage is also boosted. The internal structure of the muffler tunes and modulates the exhaust sound, too, giving your Silverado a super-aggressive presence that will make everyone within hearing sit up and take notice.
Beefy Build. The Borla ATAK Cat-Back Exhaust mixes superior materials and excellent engineering for a highly durable end product, covered by Borla’s 1 million mile warranty. The system features a single 2.75″ pipe flowing into the muffler and twin 2.25″ tailpipes, with black finished tips that exit behind the tires for an extra touch of bravado. The system is made from 300-series austenitic stainless steel, better than 400-series at resisting corrosion, and strong internally as well as outside.
Application. The Borla ATAK Split Side Exit Cat-Back Exhaust with Black Tips is specifically designed to be used on the 2014-2018 5.3L Chevrolet Silverado’s fitted with the following cab and box configurations.
