Borla'S Polyphonic Harmonizer Technology 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 to the Borla mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK systems. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow \u0026amp; power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, Borla stands behind every Polyphonic Harmonizer with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.","brand":"Borla","offers":[{"title":"Default Title","offer_id":40381485842535,"sku":"60680","price":214.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0353\/0865\/products\/2019-2023-chevrolet-silverado-1500-gmc-sierra-1500-polyphonic-harmonizer-atak-chrome-apollo-off-road-65163.jpg?v=1745058925","url":"https:\/\/apollooffroad.com\/products\/2019-2023-chevrolet-silverado-1500-gmc-sierra-1500-polyphonic-harmonizer-atak-chrome-60680","provider":"Apollo Off-Road","version":"1.0","type":"link"}
