Borla 2024 Chevrolet/GMC 1500 ZR2 & AT4X 6.2L V8 4WD 4DR ATAK Catback Exhaust w/ Turndown Tips

Starting with the 3.5-inch diameter tubing, this Borla ATAK cat-back exhaust system is built from T-304 austenitic stainless steel, a strong material that resists corrosion and ensures long-term durability. This system is specifically designed for the 6.2L V8 engine found in the 2024-2025 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X models, ensuring a precise fit with its mandrel-bent pipes that maximize exhaust flow and power.

The ATAK muffler is engineered with Borla's Polyphonic Harmonizer Technology, which uses pipes of varying diameters and lengths to create a rich, full-bodied sound without any unwanted drone. This technology helps to unleash hidden horsepower and increase exhaust velocity, contributing to a more exciting driving experience. For those who prefer a slightly quieter note, the muffler can be swapped out for part number 60679 to achieve the S-Type sound level. A valve simulator is included to prevent the Check Engine Light from illuminating, a common concern with aftermarket exhaust systems.

This system features dual 2.75-inch turndown tailpipes and is a direct bolt-on installation, meaning no welding is required. Borla backs this system with a Million-Mile Warranty, reflecting their confidence in the product's performance and longevity.
