Borla 140398 11-12 Ford Mustang 3.7L AT/MT RWD 2dr ATAK SS Catback Exhaust
Features 4.5" bright chrome on T-304 stainless steel tips. BORLA® has developed a revolutionary exhaust technology that enables their engineers to deliver unprecedented vehicle-specific control over the acoustical note of an exhaust throughout the RPM range, while retaining 100% of the power-adding capabilities of BORLA®‘s patented Multicore design.
Called ATAK® (Acoustically-Tuned Applied Kinetics), this exclusive technology (U.S. patent #5,248,859) produces the highest available dB (decibel) levels in the BORLA® street-legal lineup, and is designed for high-performance purists who prefer exhaust notes over their stereos.
The focus of ATAK® is to pump the volume while retaining clarity of sound, at the same time avoiding the drone and distortion typically found in louder exhausts. With ATAK®, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.
The development of each ATAK® system begins with extensive study of each vehicle‘s acoustical properties. The technology is based on custom-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound.
BORLA® has Cat-Back™ and/or Axle-Back ATAK® exhaust systems for a wide variety of popular applications such as Mustang GT, Camaro, Corvette, Challenger, GTR, and more in development.
Like all BORLA® exhaust products, each system is handmade in the USA by master craftspeople and features premium T-304 austenitic stainless steel construction, mandrel bending by computer-controlled CNC machinery to ensure maximum flow and a perfect fit, 4.5" bright chrome on T-304 stainless steel tips, and a Million-Mile Warranty.
