ATAK Technology - Maximum Sound Output:

ATAK (Acoustically-Tuned Applied Kinetics) technology delivers the highest available decibel levels in Borla's street-legal lineup, tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. The technology is based on specifically-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound.

Polyphonic Harmonizer Technology:

This system features Borla's Polyphonic Harmonizer Technology which 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 with no drone inside the vehicle.

Key Features:

• Dual 3.5-inch round black chrome on T-304 stainless steel tips on each tail pipe
• Ultra-smooth mandrel bends ensure maximum flow and power
• Premium T-304 stainless steel construction, superior to T-400 series knockoffs
• Precision CNC manufacturing facilitates an accurate fit
• Direct bolt-on installation with no cutting, modifications or special tools required
• Backed by Borla's Million-Mile Warranty

Important Fitment Notes:

• Factory Split Rear Exit Vehicles ONLY
