Borla 22-23 Chevrolet Silverado 1500 ZR2 & AT4X 6.2L CC SB 147.5in WB ATAK Cat-Back

Borla is known for building some of the most respected exhaust systems in motorsports, and they've brought that expertise to your 2022-2023 Chevrolet Silverado 1500 ZR2 or GMC Sierra 1500 AT4X. This ATAK cat-back system is specifically tuned for the 6.2L V8 engine, aiming to give your truck a clean, rich, and full-bodied sound without any unwanted drone. It's designed to unleash hidden horsepower and add to the driving excitement.

The system features a 3.5-inch diameter main pipe and dual 2.75-inch turn-down tailpipes. At its heart is the aggressive ATAK muffler, which uses Borla's patented Polyphonic Harmonizer Technology. This tech employs pipes of different diameters and lengths inside the muffler to create multiple exhaust notes that blend together for a unique sound. If you find the ATAK sound a bit too much, you can swap out the Polyphonic Harmonizer behind the muffler for part number 60679 to achieve the quieter S-Type sound level. The entire system is constructed from T-304 austenitic stainless steel, which is a strong material that resists corrosion and ensures long-term durability, far better than T-400 series steel. Ultra-smooth mandrel bends are used throughout to ensure maximum exhaust flow and power gains, and the precision manufacturing means it fits right the first time.

This Borla cat-back system is a direct bolt-on installation, meaning no welding is required. It's built to give your ZR2 or AT4X the distinctive sound and performance Borla is famous for. Borla backs this system with a Million-Mile Warranty, reflecting their confidence in the product's longevity and performance.
