Borla Cat-back TM & Rear Section exhaust systems that utilizes patented straight-through and multi-core technology to uncover the unused horsepower. This increased exhaust velocity is efficient to add power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts all around.

BORLA® ATAK® (Acoustically Tuned Applied Kinetics) technology is designed for high-performance purists who prefer exhaust sound over their stereos. ATAK®-equipped exhaust systems deliver the highest available dB (decibel) levels in the BORLA® street-legal lineup. And unlike inferior brands that lose significant sound quality at higher volumes, ATAK® is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.

ATAK® 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. For more details and to hear the difference, watch their ATAK® videos on the web at https://www.youtube.com/BORLA®.

Every single system is designed with premium quality 300-series austenitic stainless steel, superior to T-400 series knockoffs (such as 409) with the aim to provide you the absolute finest performance and durability.
