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

Important Notice relating to US Domestic Market Trucks & Pickups
Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.
Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.
Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
