Fits vehicles WITHOUT Ground Effects Package (GFX). System features polished T-304 stainless steel tips. BORLA has developed a revolutionary exhaust technology that enables our 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(r) (Acoustically-Tuned Applied Kinetics), this technology produces the highest available dB (decibel) levels in the BORLA street-legal lineup. The focus of ATAK(r) is to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts. With ATAK(r), 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(r) 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. A complete technology overview can be viewed at www.youtube.com/borla. Several BORLA ATAK(r) systems are currently available. For the 2010 -2013 6.2L V8 Camaro there is a Cat-Back system (PN 140356) and an Axle-Back system (PN 11788) for models without the "Ground Effects" option, and a Cat-Back system (PN 140378) and an Axle-Back system (PN 11794) designed to complement the Ground Effects kit. The Axle-Back systems retain the stock front muffler so the full effect of the ATAK(r) Sound is not realized, but they are still louder than the S-Type. Cat-Back systems for these vehicles feature a X-Pipe for increased performance and improved sound. Like all BORLA exhaust products, each system is handmade in the USA by master craftspeople and features premium, high-quality T-304 austenitic stainless steel construction, ultra-smooth mandrel bent piping, mirror-polished tips, and a Million-Mile Warranty.
