Borla Polyphonic Harmonizers

5.0 out of 5 stars 2 Customer Reviews

Borla polyphonic harmonizers replace the mufflers behind the primary mufflers in the S-type system to attain the louder sound level of an ATAK system. The technology utilizes patented units that contain pipes of different diameters and lengths, creating multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. Borla polyphonic harmonizers are manufactured from 304 stainless steel.
