ATAK® Polyphonic Harmonizer 2019-2026 Chevrolet Silverado 1500/ GMC Sierra 1500 6.2L V8 Automatic Transmission 2 & 4 Wheel Drive With Borla® "S-TYPE" Cat-Back™ System

---

Replace the small muffler behind the primary muffler in the BORLA® S-Type system with Polyphonic Harmonizer 60680 to attain the ATAK® sound level (louder than S-Type). 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 & 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.

• Can be used in select Borla(r) GM truck S-Type sound level systems to attain the ATAK(r) sound level
