Installed behind the rear axle, Borla ATAK axle-back exhaust systems replace the factory rear muffler(s) and exhaust pipe(s). Following the same exhaust path and secured using the original hangers and rubber isolators, Borla axle-back (rear section) performance exhausts are less restrictive than factory exhaust systems. Welded tips are standard on most systems.

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. Unlike inferior brands that lose significant sound quality at higher volumes, ATAK systems are tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. They are calibrated on a vehicle-by-vehicle basis and their specifically-tuned internal muffler cores deliver the most desirable sound.

Many vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the rear axle; so most Borla ATAK axle-back installations are completed in less than an hour with no cutting of the factory system. Vehicles that don't have a factory service-point require cutting, so Borla includes easy-to-follow instructions and hardware to complete the installation.

Borla pioneered the use of aircraft-grade 304 stainless steel tubing, a material with a higher content of carbon and nickel that won't rust or corrode, for the automotive exhaust aftermarket … including Borla ATAK axle-back exhaust systems with the power of race-winning Borla Multicore technology.
