The Borla S-Type Cat-Back exhaust system (part number 140859BC) is designed for the 2021-2026 Chevrolet Tahoe and GMC Yukon with the 6.2L V8. This 3.5 inch into dual 2.75 inch system uses a split rear exit with dual 4 inch round black chrome tips on T-304 stainless steel on each side for a custom appearance. It is built from premium T-304 stainless steel, superior to T-409, with ultra-smooth mandrel bends for maximum flow and CNC manufacturing for an accurate, bolt-on fit. The S-Type sound level delivers a popular, more aggressive tone with no interior drone. Because this cat-back mounts behind the factory catalytic converters, it is 50-state emissions legal. Borla exhaust is handmade in the USA and is backed by the Borla Million-Mile Warranty.
