Description BORLA 140915 Cat-Back Exhaust System 3.50", 2.75", ATAK (Turndown Tips) for CHEVROLET Silverado 1500 ZR2 2022-2023 / GMC Sierra 1500 AT4X 6.2L V8 2022-2023

This Cat-Back system is designed specifically for the 6.2L Silverado 1500 ZR2 and Sierra 1500 AT4X. The 3.5" diameter Cat-Back system features dual 2.75" turn down tail pipes, an aggressive ATAK muffler, and Polyphonic Harmonizer Technology. This technology uses patented units with pipes of different diameters and lengths to create multiple exhaust notes that harmonize for a clean, rich, full-bodied sound without drone.

The Polyphonic Harmonizer behind the muffler in the ATAK system can be replaced with muffler 60679 to achieve the "S-Type" sound level, which is quieter than ATAK. Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology to increase exhaust velocity, power, and driving excitement, while also improving fuel economy and delivering the distinctive sound.

Each system is constructed from premium T-304 austenitic stainless steel, which is superior to T-400 series materials, for enhanced performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and CNC manufacturing provides an accurate fit.
