BORLA ATAK 140839 High Performance Exhaust System for Chevrolet Corvette C8

BORLA® ATAK® (Acoustically Tuned Applied Kinetics) exhaust systems are designed for high-performance purists who prefer to listen to their Corvette C8's exhaust rather than the stereo.

ATAK® exhaust systems deliver the highest dB values ​​among the various Borla systems without compromising on sound quality, as is often the case with other loud exhaust systems.

The ATAK® technology is based on specially coordinated properties of the silencer cores, which are individually tailored to each type of vehicle in order to obtain the best sound.

Super aggressive, powerfully loud US car sound. The system is definitely too loud to be approved - but the vehicle has the sound that the true enthusiast expects.

Borla sports exhaust systems are made from high-alloy stainless steels of the T304 series according to the American AISI standard.

Developing exhaust systems for the C8 Corvette presented BORLA® engineers with unique challenges, but the team was up to the challenge. Great care has been taken to ensure the functionality and reliability of the system and the vehicle itself.
Part number 140839 includes both AFM and NPP dual mode exhaust valves.
The ATAK sound level is Borla's most aggressive level. This exhaust offers a more exciting driving experience without the drone. It features the Polyphonic Harmonizer and SwitchFire™ technology.
BORLA® Polyphonic Harmonizer Technology uses patented units that contain pipes of different diameters and lengths to produce multiple exhaust tones that harmonize with each other to deliver a clean, rich and full sound.
BORLA®'s patented SwitchFire™ design eliminates the middle, turbulent intersection of a standard X-pipe and combines combustion impulses from both sides of the engine for improved performance and customized sound.
A smartly placed heat shield prevents heat damage to the exhaust and protects your Corvette.
The system comes with 4″ bright chrome T-304 stainless steel exhaust tips and is also available with black chrome T-304 stainless steel exhaust tips (part number 140839BC) or carbon fiber exhaust tips (part number 140839CF).
The sports exhaust system is made of T-304 stainless steel.
The system is delivered in 2 boxes.

Note: After installing the BORLA® system, the control units for the AFM and NPP valves in the exhaust system should be recalibrated according to GM document ID 5406413. BORLA® recommends taking your vehicle to the nearest Chevrolet dealer to have the exhaust valves recalibrated.
