The quest for enhanced vehicle performance often leads enthusiasts to explore aftermarket exhaust systems. Among the most popular options are Borla’s S-Type and ATAK exhaust systems. This article presents a detailed comparison of the performance gains achieved by these two systems, based on dyno testing results.
Understanding Exhaust Systems
Exhaust systems play a crucial role in optimizing engine performance by improving airflow and reducing back pressure. The design and materials used in these systems can significantly affect a vehicle’s horsepower, torque, and overall efficiency.
Borla Exhaust Systems Overview
Borla is a well-known brand in the aftermarket exhaust industry, recognized for its high-quality performance exhaust systems. The company offers a variety of options, including the S-Type and ATAK systems, each designed to cater to different performance needs and sound preferences.
S-Type Exhaust System
The S-Type exhaust system is designed to provide a moderate sound level while enhancing performance. It is ideal for those who want an aggressive sound without being overly loud. The S-Type system features:
- Stainless steel construction for durability.
- Mandrel-bent tubing for smooth airflow.
- A performance-oriented muffler design.
ATAK Exhaust System
The ATAK system, which stands for “Acoustically-Tuned Applied Kinetics,” is designed for maximum sound and performance. It is perfect for enthusiasts who crave a louder, more aggressive exhaust note. Key features of the ATAK system include:
- High-flow muffler design for increased sound levels.
- Precision-engineered to minimize back pressure.
- Stainless steel components for longevity.
Dyno Testing Methodology
To accurately compare the performance gains from the Borla S-Type and ATAK exhaust systems, a series of dyno tests were conducted. The tests were performed under controlled conditions to ensure consistency and reliability of the results.
Test Vehicle Specifications
The tests were conducted on a standard performance vehicle equipped with a stock exhaust system. The following specifications were noted:
- Engine: 5.0L V8
- Power Output: 400 HP
- Torque: 400 lb-ft
Testing Procedure
Each exhaust system was installed on the test vehicle, and multiple runs were conducted on the dynamometer to measure horsepower and torque outputs. The data collected was analyzed to determine the performance differences between the two systems.
Performance Gains: S-Type vs. ATAK
The results of the dyno testing revealed notable differences in performance gains between the S-Type and ATAK exhaust systems. Below are the key findings:
Horsepower Gains
The horsepower gains achieved by each system were as follows:
- S-Type: +15 HP
- ATAK: +25 HP
Torque Gains
The torque gains observed during the testing were:
- S-Type: +10 lb-ft
- ATAK: +20 lb-ft
Sound Comparison
In addition to performance gains, sound is a critical factor for many enthusiasts. The audio characteristics of the S-Type and ATAK exhaust systems differ significantly:
S-Type Sound Profile
The S-Type exhaust produces a deep, aggressive tone that enhances the driving experience without being overly intrusive. It is suitable for daily driving while still providing an exhilarating sound during acceleration.
ATAK Sound Profile
The ATAK system, on the other hand, delivers an intense and loud sound that is sure to turn heads. It is designed for those who want their vehicle to make a statement, especially during high RPMs.
Conclusion
In conclusion, both the Borla S-Type and ATAK exhaust systems offer significant performance gains and distinctive sound profiles. The choice between the two ultimately depends on the driver’s preferences regarding sound level and performance needs. The dyno results clearly indicate that the ATAK system provides greater horsepower and torque gains, making it an excellent option for performance enthusiasts.
Final Thoughts
When selecting an exhaust system, it’s essential to consider not just the performance gains but also how the sound will impact your driving experience. Both systems have their merits, and potential buyers should weigh their options carefully to find the best fit for their vehicle and driving style.
