Product Overview

Features bright chrome on 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, and is designed for high-performance purists who prefer exhaust notes over their stereos. 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. The distance from the exhaust manifold to the rear bumper, the shape of the underbody shielding, the amount of ground clearance, all these factors affect the sound, and they're different on each vehicle. With ATAK(r) we take all this into account, and the result will blow you away, all with no drone inside the cabin of the vehicle says company VP of Sales & Marketing, David Borla 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.

Exhaust System, ATAK, Rear Section, Dual, Stainless, Natural, Split Rear Exit, Ford, 5.0L, Kit

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.
