Borla 22-23 Chevrolet Silverado 1500 ZR2 & AT4X 6.2L CC SB 147.5in WB ATAK Cat-Back

This system features the aggressive BORLA(r) ATAK(r) muffler and Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound without any drone. Replace the Polyphonic Harmonizer behind the muffler in the ATAK(r) system with muffler 60679 to attain the "S-Type" sound level (quieter than ATAK(r)). It was designed specifically for the Silverado 1500 ZR2 and Sierra 1500 AT4X and features turn down tail pipes. BORLA(r) Cat-Back(tm) & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA(r) Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA(r) stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
