This is the most aggressive muffler section that Borla produces for the F80/F82 M3/M4. Their ATAK system - Acoustically Tuned Applied Kinetics - allows a high volume exhaust note without drone or distortion. Borla manages the sound waves inside the exhaust to produce an exhaust note that maintains its tone as revs rise. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. This exclusive technology 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.
For an exhaust that really emphasizes your BMW's motorsport heritage, the Borla ATAK System is the ideal choice.
