Description

ExhstSysKt

This system features the aggressive ATAK(r) sound and exits through 3.5" X 3.28" bright chrome on T-304 stainless steel tips. ATAK(r), Acoustically-Tuned Applied Kinetics, 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. This is our most aggressive sound. Even though the sound on the exterior is uncompromising, the sound in the cabin is devoid of harsh resonance, a product of painstaking engineering and over 40 years of experience. Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, Borla(r) stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Product Overview

BORLA has announced the development of a revolutionary new exhaust technology that enables their 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 (Acoustically-Tuned Applied Kinetics), this exclusive technology (U.S. patent #5,248,859) 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 is to pump the volume while retaining clarity of sound, at the same time avoiding the drone and distortion typically found in louder exhausts. With ATAK, 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 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. BORLA is now shipping Cat-Back and/or Rear Section ATAK exhaust systems for a wide variety of popular applications.

Like all BORLA exhaust products, each system is handmade in the USA by master craftspeople and features premium 300-Series austenitic stainless steel construction, mandrel bending by computer-controlled CNC machinery to ensure maximum flow and a perfect fit, mirror-polished tips, and a Million-Mile Warranty

Exhaust System, ATAK, Rear Section, Single In/Dual Out, Stainless, Natural, Split Rear Exit, Jeep, 3.6L, 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.
