Introduction: Finding Your Vehicle's True Character

An exhaust system is more than just a pipe. It is the voice of your engine. It broadcasts your car's performance intent before you even touch the throttle. For car enthusiasts, upgrading the exhaust is one of the most satisfying modifications because it provides an immediate and visceral connection to the driving experience. Among aftermarket manufacturers, Borla stands as a titan of the industry, revered for its American-made quality, advanced acoustic engineering, and distinct sound profiles.

When browsing Borla's lineup, two names consistently dominate discussions: the Borla S-Type and the Borla ATAK. At first glance, they seem similar—both are cat-back systems made from high-quality T-304L stainless steel, both promise horsepower gains, and both carry Borla's legendary Million-Mile Warranty. However, they are engineered for fundamentally different drivers. The S-Type is a masterclass in refinement and balanced aggression, designed for those who want performance without overwhelming noise. The ATAK is an unapologetic assault on the senses, built for drivers who want maximum volume and a raw, track-ready personality.

Choosing between the two requires a deep understanding of your driving habits, your tolerance for cabin drone, and your performance goals. This comprehensive guide analyzes the engineering, sound characteristics, and real-world performance of the Borla S-Type vs. the Borla ATAK, providing you with the knowledge to make the best investment for your vehicle and your driving style.

Understanding Borla's Engineering Philosophy

To appreciate the differences between the S-Type and ATAK, it is necessary to understand the company behind them. Borla Performance Industries was founded in 1978 by Alex Borla, a motorsport engineer driven by a passion for performance and precision manufacturing. Based in Johnson City, Tennessee, Borla has spent over four decades refining exhaust technology, supplying components for everything from NASCAR and IndyCar to production vehicles and off-road trucks.

Borla's commitment to quality starts with materials. They exclusively use T-304L aircraft-quality stainless steel. This grade of steel offers superior corrosion resistance compared to T-409 often used by competitors, ensuring the exhaust looks and performs well for the life of the vehicle. Their manufacturing process includes CNC mandrel bending, which prevents the pipe from collapsing at bends, ensuring smooth exhaust flow and maximum power production.

Each system is engineered using Borla's patented sound technology, which balances loudness with acoustic quality. The goal is to eliminate unpleasant frequencies while enhancing the engine's natural tone. Whether you choose the S-Type or the ATAK, you are getting an exhaust built to exacting tolerances. The primary variable is the sound tuning and flow path, which dictates the driving experience.

Borla S-Type Exhaust: The Art of Refined Performance

The S-Type is often described as the "sweet spot" of the Borla lineup. The "S" stands for "Sport," and it perfectly encapsulates the system's goal: to provide a noticeable performance upgrade and aggressive sound without crossing into territory that is fatiguing for daily driving.

Sound Profile: Deep, Rich, and Controlled

The sound of the S-Type is characterized by a deep, mellow rumble at idle that evolves into a refined roar under acceleration. Unlike systems that rely solely on volume to make an impression, the S-Type is meticulously tuned to eliminate annoying frequencies, such as high-pitched rasp or droning resonance at highway speeds.

Borla achieves this through its patented Reflective Sound Cancellation technology. Inside the muffler, specifically tuned reflectors cancel out harsh sound waves (drone) while amplifying the desirable tones. The result is an exhaust note that is significantly louder than stock—roughly 30-50% louder depending on the vehicle—but remarkably civilized when cruising. When you step on the gas, the S-Type delivers a deep, authoritative bark that signals performance without screaming for attention. It is an exhaust system that invites you to drive harder, knowing the soundtrack will elevate the experience without annoying your neighbors or your passengers.

For those driving European sedans, modern muscle cars, or sports coupes, the S-Type provides an exotic, high-end tone. It adds a layer of sophistication often missing from louder, more aggressively tuned exhausts.

Performance Benefits: Low-End Torque and Throttle Response

Performance gains from the S-Type are most noticeable in the low-to-mid RPM range. By improving exhaust flow with a larger diameter, mandrel-bent piping and a high-flow straight-through muffler design, the S-Type reduces back pressure. This reduction allows the engine to expel exhaust gases more efficiently, leading to improved throttle response and a noticeable bump in horsepower and torque.

Drivers frequently report that the S-Type makes their vehicle feel "lighter" and more responsive to pedal inputs. Specific dyno-proven gains vary by vehicle, but Borla typically advertises increases of 5-15 horsepower at the wheels. While peak gains are modest, the real-world improvement in driveability—especially when merging onto highways or passing on two-lane roads—is substantial. The S-Type capitalizes on the area of the power band where most people drive daily, making it an excellent performance upgrade for a street-driven vehicle.

Build Quality and Materials

The S-Type is built with the same T-304L stainless steel as its more aggressive sibling. It features large, polished (or brushed depending on application) exhaust tips that are laser-etched with the Borla logo. The system is designed for a direct fit, utilizing factory-style hangers and flanges. The included hardware is also stainless steel, preventing rust and making installation straightforward for a qualified mechanic or experienced DIYer. Like all Borla products, the S-Type carries the Million-Mile Warranty, which covers defects in materials and workmanship.

Who Should Buy the Borla S-Type?

  • Daily Drivers: If your car is your primary mode of transportation and you spend significant time on the highway, the S-Type's drone-free cruising makes it the superior choice.
  • Performance Seekers: If you are building a car for autocross, road courses, or spirited back-road driving, the improved throttle response and low-end torque provide tangible benefits.
  • Discreet Enthusiasts: If you want your car to sound fast without attracting unwanted attention from law enforcement or antagonizing your neighbors, the S-Type offers the perfect balance.

Borla ATAK Exhaust: Maximum Aggression, Maximum Sound

ATAK stands for "Advanced Technology Acoustic Kinetics." This system is the pinnacle of Borla's sound engineering and is designed for enthusiasts who prioritize volume and aggression above all else. The ATAK is built to turn heads, set off car alarms, and provide an adrenaline-pumping experience every time the engine fires up.

Sound Profile: Raw, Loud, and Unfiltered

The Borla ATAK is significantly louder than the S-Type. Depending on the application, it can be up to 100% louder than the factory exhaust. The tone is more aggressive, featuring a higher-pitched snarl at wide-open throttle and pronounced crackles and pops on deceleration. This is the sound of a race car on the street.

Unlike the S-Type, which uses sound cancellation to eliminate drone, the ATAK uses a more direct flow path with less internal baffling. This design prioritizes maximum volume and a raw, mechanical edge. As a result, there is noticeably more cabin drone at steady cruising speeds compared to the S-Type. For some, this drone is an acceptable trade-off for the sheer auditory thrill. For others, it makes long highway trips less enjoyable. The ATAK does not apologize for its nature. It is loud, it is brash, and it demands attention.

The ATAK is ideal for V8 muscle cars like the Mustang GT or Camaro SS, where it amplifies the deep, guttural American V8 rumble. It also performs exceptionally on trucks like the Ford Raptor, giving them a commanding presence. On turbocharged four-cylinder or six-cylinder engines, the ATAK introduces a sharper, more exotic note that mimics high-strung performance machinery.

Performance Benefits: High-RPM Horsepower

While the S-Type optimizes low-to-mid range torque, the ATAK is tuned for maximum top-end horsepower. The less restrictive design allows the engine to breathe freely at high RPMs, reducing exhaust back pressure to its absolute minimum. On the dyno, the ATAK often shows slightly higher peak horsepower numbers compared to the S-Type, particularly in engines that are cammed or heavily modified.

For track-day enthusiasts or drivers who spend most of their time above 4,000 RPM, the ATAK provides the flow necessary to support aggressive driving. The reduced back pressure helps the engine rev more freely, contributing to a sense of urgency as the tachometer climbs toward the redline. It pairs exceptionally well with other performance modifications like cold air intakes, headers, and performance tunes.

Build Quality and Materials

Constructed from the same T-304L stainless steel as the S-Type, the ATAK offers the same corrosion resistance and robustness. The tips are often larger and more aggressive in design. Despite the increased flow, the ATAK retains Borla's precise fitment and includes all necessary hardware for installation. It is backed by the same comprehensive Million-Mile Warranty, proving that aggressive sound does not mean sacrificing quality or longevity.

Who Should Buy the Borla ATAK?

  • Weekend Warriors: If your car is a second or third vehicle used primarily for fun, the ATAK's raw sound is a constant source of joy.
  • Track Enthusiasts: If you frequently visit drag strips or road courses, the ATAK's high-RPM power and weight reduction are beneficial.
  • Show Cars: For vehicles that are displayed at meets and shows, the ATAK provides the auditory spectacle that draws a crowd.
  • Unapologetic Enthusiasts: If you believe a performance car should sound like a performance car, and you accept the compromises in cabin noise, the ATAK is the definitive choice.

Head-to-Head Comparison: S-Type vs. ATAK

Choosing between these two systems requires evaluating specific trade-offs. The following direct comparison addresses the key factors that influence the ownership experience.

Sound Level and Drone

  • S-Type: Louder than stock by 30-50%. Minimal to no drone at cruising speeds (1,500-2,500 RPM). Deep, exotic tone. Suitable for long road trips.
  • ATAK: Louder than stock by 60-100%+. Noticeable drone in the 1,500-2,500 RPM range. Aggressive, raw tone. Can be fatiguing on long drives.

Power Delivery

  • S-Type: Optimized for low-to-mid range torque. Improves throttle response and daily driveability. Peak gains are solid but focused on real-world driving.
  • ATAK: Optimized for top-end horsepower. Shines at high RPMs. Slightly better peak numbers on a dyno. Ideal for modified engines.

Construction and Warranty

  • Both: T-304L Aircraft-Quality Stainless Steel, Mandrel Bent Tubing, Million-Mile Warranty, direct fit installation.
  • Difference: ATAK may feature larger diameter tips. Internal muffler construction is different to prioritize flow over sound refraction.

Cost Considerations

Pricing for S-Type and ATAK systems is generally very similar for the same vehicle. Borla prices them competitively, recognizing that the choice is one of preference rather than budget. If there is a price difference, it is typically small, often less than $100. This makes the decision entirely about the desired sound and performance character, not the cost of entry.

Installation Differences

Installation complexity is identical for both systems. Borla designs their cat-back exhausts to utilize factory hangers and clamps. They often include detailed instructions. A typical installation can be completed in 2-4 hours with basic hand tools (jack, jack stands, wrench set, penetrating oil). Neither system requires welding, making them accessible to DIY enthusiasts.

Frequently Asked Questions

Is the Borla ATAK too loud for a daily driver?

This depends on your tolerance for noise and cabin drone. Many people daily drive cars with ATAK exhausts and enjoy the constant feedback. Others find the drone fatiguing after an hour on the highway. If your commute involves significant highway cruising and you value conversation or music clarity, the S-Type is a more livable choice.

Does the Borla S-Type drone on the highway?

Generally, no. Borla's Reflective Sound Cancellation technology is specifically designed to eliminate the frequencies that cause drone. Most users report that the S-Type is quiet and civilized at a steady 65-75 mph, only producing its aggressive note under hard acceleration.

Which exhaust gives more horsepower, S-Type or ATAK?

On most naturally aspirated engines, the ATAK produces slightly higher peak horsepower (2-5 hp typically) due to its less restrictive design. However, the S-Type often produces more torque in the low-to-mid RPM range, which feels faster during daily driving. For modified cars or forced induction setups, the ATAK's advantages become more pronounced at high RPMs.

Will a Borla exhaust void my vehicle warranty?

In the United States, the Magnuson-Moss Warranty Act protects consumers. A manufacturer cannot void a vehicle warranty simply because an aftermarket part is installed. They must prove that the aftermarket part caused the specific failure. A cat-back exhaust like the Borla S-Type or ATAK is very unlikely to cause engine damage. Borla systems are designed to be a direct replacement for the factory system.

Can I install the exhaust myself?

Yes, if you have moderate mechanical ability. Cat-back exhausts are among the easier modifications to perform. You will need to lift the vehicle, remove the old exhaust (which may require penetrating oil for rusted bolts), and hang the new Borla system. The sections connect with clamps, and the system uses factory mounting points. It is a rewarding Saturday project.

Does Borla offer a Touring exhaust?

Historically, Borla offered a "Touring" system that was quieter than the S-Type. In many applications, the S-Type has replaced the Touring as the entry-level performance upgrade. There is also the Borla "Pro XS" muffler for custom systems. However, the S-Type represents the lowest volume option for most complete cat-back systems today.
