ATAK Cat-Back Exhaust System 3.5-Inch to Dual 2.25-Inch

The Borla 140577 ATAK Cat-Back exhaust system is engineered to deliver an aggressive sound for your 2014-2018 Chevrolet Silverado 1500 or GMC Sierra 1500 equipped with the 6.2L V8 engine. This system features a 3.5-inch diameter inlet that splits into dual 2.25-inch outlets, culminating in 4-inch round, rolled, angle-cut tips exiting on the truck's side. The ATAK sound level is Borla's most aggressive offering, providing a deep growl without introducing unwanted interior drone. Constructed from premium T-304 stainless steel, this system is built for superior performance and longevity, outlasting T-400 series alternatives. Borla utilizes ultra-smooth mandrel bends to maximize exhaust flow and power gains. The precision manufacturing ensures an accurate fit, and the system is backed by Borla's Million-Mile Warranty. This Cat-Back system is specifically designed for Extended Cabs with a Standard Bed (143.5" wheelbase) and Crew Cabs with a Short Bed (143.5" wheelbase). It is compatible with both automatic and manual transmissions, as well as both 2-wheel and 4-wheel drive configurations for the specified models and engine.
