The 3.5 inch into dual 2.75 inch system fits factory split rear exit trucks only and includes a valve simulator to keep the Check Engine Light off. It does not fit ZR2 or AT4X models. Adapter 60706 is required for Crew Cab with Standard Bed (6 foot 7 inch) 157 inch wheelbase vehicles. This system features dual 3.5 inch round black chrome on T-304 stainless steel tips on each tail pipe, and installation requires removing the factory valance tips. The aggressive ATAK sound level delivers a loud, head-turning tone with no drone inside the cabin. Borla Cat-Back and Axle-Back systems use patented straight-through, multi-core technology to free up hidden horsepower, and the added exhaust velocity brings more power, driving excitement, and the distinctive Borla Sound of Power. The system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate, long-lasting fit. Like all Borla exhaust, it is handmade in the USA. As a street Cat-Back system that mounts behind the factory catalytic converters, it is 50-state emissions legal. It is 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 type: ATAK Cat-Back exhaust\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK (S-Type with muffler 60679)\u003c\/li\u003e\n\u003cli\u003eTechnology: Polyphonic Harmonizer\u003c\/li\u003e\n\u003cli\u003ePipe diameter: 3.5 in into dual 2.75 in\u003c\/li\u003e\n\u003cli\u003eValve simulator included\u003c\/li\u003e\n\u003cli\u003eFitment: factory split rear exit only; excludes ZR2 and AT4X\u003c\/li\u003e\n\u003cli\u003eTips: dual 3.5 in round black chrome on T-304 stainless steel (requires removing factory valance tips)\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 stainless steel\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: 140997BC\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2025 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2025 GMC Sierra 1500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhich vehicles does the Borla 140997BC Cat-Back fit?\u003c\/h5\u003e\u003cp\u003eIt fits the applicable 6.2L V8 Chevrolet Silverado 1500 and GMC Sierra 1500 with factory split rear exit, excluding ZR2 and AT4X models.
