ATAK Technology:

Unlike conventional loud exhaust systems that produce distortion and drone, ATAK technology functions like a graphic equalizer to shape and focus sound waves for optimum high-volume output. Each system is developed through extensive study of vehicle-specific acoustical properties, with custom-tuned internal muffler cores calibrated to deliver the most desirable sound characteristics for each application.

Handcrafted in the USA by master craftspeople, this exhaust system is backed by Borla's Million-Mile Warranty, demonstrating their confidence in quality and durability. The system delivers an aggressive, race-inspired tone that's perfect for performance purists who prefer their exhaust note over their stereo.
