The Borla 140995 is an S-Type cat-back exhaust system for 2024-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 6.2L V8, designed for factory split rear exit vehicles. The 3.5 inch into dual 2.75 inch system uses Borla's patented straight-through, multi-core design along with Polyphonic Harmonizer Technology to produce the classic S-Type sound without interior drone, and it includes a valve simulator that keeps the check engine light from coming on. Each system is built from T-304 austenitic stainless steel with mandrel bends and CNC-manufactured components for an accurate fit, and it finishes in dual 3.5 inch by 3.28 inch bright chrome T-304 stainless tips on each tail pipe. It does not fit ZR2 or AT4X models, and installation requires removal of the factory valance tips. Borla exhaust systems are handmade in the USA and backed by the Borla Million-Mile Warranty.
