The 3.5 inch diameter system uses dual 2.75 inch turn-down tail pipes and features the aggressive Borla ATAK muffler with Polyphonic Harmonizer technology, which uses patented units containing pipes of different diameters and lengths to create multiple exhaust notes that harmonize into a clean, rich, full-bodied sound with no interior drone. It includes a valve simulator to prevent the check engine light from coming on. The ATAK Polyphonic Harmonizer can be replaced with muffler 60679 to step down to the quieter S-Type sound level. Borla cat-back and axle-back systems use patented straight-through, multi-core technology to free hidden horsepower, add exhaust velocity, and produce the distinctive Borla Sound of Power. As a cat-back system that mounts behind the factory catalytic converters, it is 50-state emissions legal. Each system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and precision CNC-manufactured components for an accurate, bolt-on fit. Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem: ATAK cat-back exhaust\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 austenitic stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: patented straight-through, multi-core\u003c\/li\u003e\n\u003cli\u003eSystem diameter: 3.5 in with dual 2.75 in turn-down tail pipes\u003c\/li\u003e\n\u003cli\u003eTips: 2.75 in turn-down tail pipes\u003c\/li\u003e\n\u003cli\u003eValve simulator included to prevent check engine light\u003c\/li\u003e\n\u003cli\u003eDowngradeable to S-Type sound with muffler 60679\u003c\/li\u003e\n\u003cli\u003eEmissions: 50-state emissions legal\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 141004\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2024 Chevrolet Silverado 1500 ZR2\u003c\/li\u003e\n\u003cli\u003e2025 Chevrolet Silverado 1500 ZR2\u003c\/li\u003e\n\u003cli\u003e2024 GMC Sierra 1500 AT4X\u003c\/li\u003e\n\u003cli\u003e2025 GMC Sierra 1500 AT4X\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the Borla 141004 cat-back fit?\u003c\/h5\u003e\u003cp\u003eIt fits the 2024 and 2025 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X with the 6.2L V8 engine.\u003c\/p\u003e\u003ch5\u003eIs the Borla 141004 cat-back legal for street use?\u003c\/h5\u003e\u003cp\u003eYes.
