Borla 2019 Chevrolet Silverado/Sierra 1500 6.2L Atak 3.5in Diameter Polyphonic Harmonizer

This Borla Polyphonic Harmonizer is built from T-304 stainless steel, which is a stronger material than T-400 series steel, offering better performance and durability. It's designed to replace the smaller muffler found behind the primary muffler in your Borla S-Type exhaust system, specifically to achieve the louder ATAK sound level. The unique Polyphonic Harmonizer technology uses internal pipes of varying diameters and lengths to create multiple exhaust notes that blend together. These harmonized notes then work with the Borla mufflers to produce a clean, full-bodied sound that’s deeper and richer than the S-Type system alone.

Borla uses ultra-smooth mandrel bends in their construction to ensure exhaust gases flow as freely as possible, which helps with power output. The precision manufacturing means this harmonizer fits right into place with your existing Borla S-Type system. If you're looking to turn up the volume and add more character to your Silverado or Sierra's exhaust note, this is a solid option.

This part is designed to be installed with a Borla S-Type cat-back system on 6.2L V8 engines with automatic transmissions, whether you have a 2-wheel or 4-wheel drive truck. Borla backs this harmonizer with a Million-Mile Warranty.
