The Borla Touring cat-back exhaust system is built for 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks with the 5.3L V8 and the factory split rear exit, including Trail Boss models. The 3 inch into dual 2.75 inch system delivers the mellow Touring sound level with no drone inside the cabin and exits through dual 3.5 inch round black chrome T-304 stainless steel tips on each tail pipe. Installation requires removal of the factory valance tips. Bright chrome and carbon fiber tip versions are also available. Borla recommends cleaning the black chrome tips with hot water and a microfiber cloth rather than stainless polish. Add adapter 60708 for crew cab models with the standard bed and 157 inch wheelbase. Borla cat-back systems use patented straight-through, multi-core technology to free hidden horsepower while adding exhaust velocity, driving excitement, and fuel economy, backed by the distinctive Borla Sound of Power. Each system is built from premium T-304 stainless steel with ultra-smooth mandrel bends and CNC-precise construction for an accurate fit. Because it mounts behind the factory catalytic converters, this cat-back system is 50-state emissions legal. Borla exhaust is handmade in the USA and backed by a Million-Mile Warranty.
