This Borla ATAK Cat-Back system was designed specifically for the 6.2L Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X. The 3.5 inch diameter system runs dual 2.75 inch turn-down tailpipes and delivers the aggressive Borla ATAK sound level using Polyphonic Harmonizer technology for a clean, rich, full-bodied tone with no drone. Swapping in muffler 60679 steps the system down to the S-Type sound level. Borla Cat-Back systems use patented straight-through, multi-core technology to free hidden horsepower, add exhaust velocity, and deliver the distinctive Borla Sound of Power. Each system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate fit. As a street cat-back system that mounts behind the factory catalytic converters, it is 50-state emissions legal. Like all Borla exhaust systems, it is handmade in the USA from premium T-304 austenitic stainless steel and backed by the Borla Million-Mile Warranty.
