If you own a Chevy Silverado and want to enhance its performance and sound, Borla exhaust systems are an excellent choice. Known for quality and durability, Borla offers a range of options suitable for various Silverado models. In this review, we explore some of the top Borla exhaust systems to help you make an informed decision. We will cover sound profiles, installation considerations, material quality, and real-world performance gains so you can choose the system that best matches your driving style and budget.

Why Borla Exhaust Systems Stand Out for the Chevy Silverado

Borla has been a leader in aftermarket exhaust technology for decades, and their systems for the Chevy Silverado are engineered with the same precision that has made them a favorite among enthusiasts and professionals alike. Every Borla system starts with aerospace-grade stainless steel, ensuring it resists corrosion and lasts as long as your truck. Unlike many competitors who use mild steel or aluminized coatings, Borla uses 100% 304 stainless steel for the entire system — from the muffler body to the tailpipe tips. This means your exhaust will look and perform like new even after years of exposure to salt, mud, and extreme temperatures.

Another key advantage is Borla’s straight-through perforated core technology, often called “Borla’s patented technology.” This design eliminates restrictive baffles and chambers that trap exhaust gases, allowing for a free-flowing path that reduces backpressure and unlocks hidden horsepower. The result is not only better performance but also a signature sound that is aggressive without being obnoxious at highway speeds. Borla invests heavily in research and development, using computer-aided tuning to produce specific sound frequencies for each application. Whether you prefer a deep rumble or a sharp crackle, there is a Borla system tuned for your Silverado.

Additionally, Borla stands behind its products with industry-leading warranties. Most cat-back systems come with a Million-Mile Warranty, which covers defects in materials and workmanship for as long as you own the vehicle. This level of confidence is rare in the aftermarket world and reflects the durability of their construction. For Silverado owners who put their trucks to work every day or tow heavy loads, a Borla exhaust is a long-term investment that pays back in sound, power, and reliability.

Understanding Borla’s Sound Categories: Touring, S-Type, and ATAK

Before diving into specific product recommendations, it helps to understand Borla’s three main sound profiles. Each one is engineered to deliver a different auditory experience while still improving exhaust flow and horsepower. The names are consistent across most of Borla’s product lines, so knowing the differences will help you compare systems quickly.

Borla Touring (Moderate Sound)

The Touring system is Borla’s quietest option, designed for those who want a subtle upgrade over stock without attracting unwanted attention. It produces a smooth, deep tone at idle and a moderate roar under acceleration. At cruising speeds, it is barely louder than factory, making it ideal for daily drivers who still want a bit of personality. The Touring system uses Borla’s patented muffler design but with more sound-absorbing material inside the resonator section to minimize drone and overall volume. It is a favorite among Silverado owners who use their trucks for long highway commutes or towing, where cabin comfort is important.

Borla S-Type (Sport Sound)

The S-Type strikes a balance between the mild Touring and the aggressive ATAK. It delivers a sportier, more aggressive tone that announces your presence without being overwhelming. The S-Type is noticeably louder than Touring at wide-open throttle, yet remains refined during light driving. It features a more direct flow path than the Touring, which gives it a crisper sound and slightly higher peak horsepower gains. If you want a system that sounds like a performance truck should and can still hold a conversation in the cab, the S-Type is the sweet spot.

Borla ATAK (Maximum Aggression)

ATAK stands for Acoustically Tuned Applied Kinetics. It is Borla’s loudest and most performance-oriented cat-back system. The ATAK uses a larger, straight-through muffler with minimal internal damping, producing a raw, high-volume exhaust note that turns heads. At idle, it has a deep, menacing rumble. Under heavy acceleration, it screams with authority. The ATAK is not for everyone — it can be too loud for some neighborhoods or for drivers who want a quiet cabin. However, for Silverado owners who crave maximum sound and aren’t afraid to let their V8 sing, the ATAK delivers an unforgettable experience.

Top Borla Exhaust Systems for Chevy Silverado – Detailed Reviews

Now that we have established the sound categories, let’s look at specific systems available for the Chevy Silverado (1500, 2500HD, 3500HD) across various model years. We will focus on cat-back systems, which include everything from the catalytic converter back to the tailpipe, making installation straightforward with no cutting required.

1. Borla ATAK Cat-Back Exhaust System (Model 140732)

The ATAK system is the crown jewel of Borla’s lineup for the Silverado. Designed for maximum performance and sound, it is offered for both 5.3L and 6.2L V8 engines, as well as the 6.6L gas V8 found in heavy-duty models. The system includes a large-diameter 304 stainless steel pipe, a free-flowing muffler, and dual polished tips. The cold-side pipe is mandrel-bent to ensure smooth flow, and all clamps and hangers are included for a bolt-on installation.

Performance Gains: According to Borla, the ATAK system can add up to 10–15 horsepower and 15–20 lb-ft of torque at the rear wheels, depending on the engine and existing mods. The gains are most noticeable in the mid-range, where the improved flow helps the engine breathe better during passing and towing.

Sound: The ATAK is loud. There is no other way to put it. It produces a deep, aggressive bark on start-up and a constant rumble at idle. Under load, it howls with a racing-inspired note. In-cab drone is minimal thanks to Borla’s resonator tuning, but it is still louder than stock at highway speeds. This system is best suited for drivers who want their Silverado to sound like it means business.

Installation: The ATAK is a direct-fit cat-back system. Most DIYers can install it in under two hours with basic hand tools. The instructions are clear, and the parts are well packaged. No welding or fabrication is required.

2. Borla S-Type Cat-Back Exhaust System (Model 140725)

The S-Type is the most popular choice among Silverado owners who want a noticeable upgrade without going extreme. It is available for the same engine configurations as the ATAK and uses the same high-grade stainless steel construction. The S-Type muffler is slightly different internally, providing a more balanced sound profile that is aggressive when you want it but tame when you need it.

Performance Gains: Horsepower gains are similar to the ATAK, typically in the 8–12 hp range. Torque gains are also comparable. The S-Type does not sacrifice much in terms of power while offering a more livable daily experience.

Sound: The S-Type has a deep, muscular tone that is about 30% louder than stock at full throttle but only slightly louder during light acceleration. It has a characteristic Borla “crackle” on deceleration that many enthusiasts love. Drone is very well controlled, making it an excellent choice for trucks that see double duty as daily drivers and weekend warriors.

Installation: Identical to the ATAK in terms of complexity. All hardware is included, and the system bolts directly to the factory catalytic converter flange.

3. Borla Touring Cat-Back Exhaust System (Model 140722)

For Silverado owners who want a refined upgrade, the Touring system delivers a subtle improvement in sound and performance without drawing unwanted attention. It is the quietest option in Borla’s lineup, yet still offers better flow than the restrictive factory exhaust. The Touring system is an excellent choice for those who tow frequently or have a long commute and prefer a quiet cabin.

Performance Gains: Expect modest gains of 5–8 horsepower and 8–12 lb-ft of torque. While not as dramatic as the S-Type or ATAK, these gains are still noticeable when accelerating onto highways or climbing grades with a trailer.

Sound: The Touring system is only slightly louder than stock at idle. Under acceleration, it produces a smooth, deep note that is more refined than aggressive. There is no drone, and the overall volume remains comfortable for passengers. This system is perfect for Silverados used as daily drivers or work trucks where a loud exhaust might be inappropriate.

Installation: Same straightforward bolt-on procedure. The Touring system uses Borla’s standard clamp-and-hanger setup, which allows for easy removal or adjustment if needed.

4. Borla XR-1 Race Muffler System (Model 20062)

While Borla’s cat-back systems are designed for street use, the XR-1 line is a separate category aimed at racing and extreme performance. Unlike the cat-back systems, the XR-1 is a muffler replacement that can be welded into an existing exhaust system or used as a standalone race muffler. It is much smaller and lighter than Borla’s street mufflers, with a straight-through design that offers minimal flow restriction. This system is not CARB compliant and does not come with a smog legal warranty, so it should only be used on off-road or track-only vehicles.

Performance Gains: The XR-1 can free up significant horsepower, especially when paired with headers and a tune. Gains of 15–20 hp are possible on modified engines. However, because it removes much of the sound deadening, the noise level is extreme. Expect a raw, open-pipe sound that is far too loud for most street applications.

Sound: The XR-1 produces a sharp, aggressive tone that is unmistakably race-inspired. It is ear-splitting under hard acceleration and drones heavily at highway speeds. Only serious enthusiasts should consider this for street use, and even then, local noise ordinances may be an issue.

Installation: The XR-1 is an inline muffler that must be welded into the exhaust system. Professional installation is recommended unless you have welding experience and the proper equipment.

5. Borla Pro XS Muffler (Single and Dual Versions)

The Borla Pro XS is another muffler-level upgrade that is less extreme than the XR-1 but more aggressive than a standard cat-back. It is available in single and dual configurations to fit the Silverado’s dual-exit factory bumpers. The Pro XS uses Borla’s patented sound technology to produce a deep, powerful tone without the harshness of a straight pipe. Many Silverado owners choose this as a muffler swap to retain factory pipes while upgrading the sound.

Performance Gains: Modest gains of 3–5 hp with a muffler-only swap. The real benefit is sound quality and a slight reduction in backpressure.

Sound: The Pro XS offers a balanced sound that is louder than the Touring but quieter than the S-Type. It has a nice rumble at idle and a clean note under acceleration. It works well with stock exhaust piping and does not introduce drone.

Installation: A muffler swap requires cutting the existing exhaust and welding the new unit in place. Some shops can do this in about an hour, and the parts cost is significantly lower than a full cat-back system.

Installation Tips and Common Questions

Installing a Borla cat-back exhaust on your Silverado is one of the easiest performance upgrades you can do. The systems come with detailed instructions, and most require only basic tools like a ratchet, socket set, and penetrating oil for the factory bolts. Here are a few tips to ensure a smooth installation:

  • Penetrating oil is your friend. Factory exhaust hangers and bolts can be rusted. Spray them with a penetrating lubricant the night before you plan to install. This will save you time and frustration.
  • Use a shadow board or cardboard to lay out the parts. Borla includes every clamp and hanger you need. Lay them out in order before you begin to avoid mix-ups.
  • Leave all connections loose until the entire system is hung. Tighten gradually, working from the front to the rear, to ensure proper alignment and clearance. This helps prevent rattles against the underbody.
  • Check for leaks after installation. Start the engine and listen for any hissing sounds at the joints. If you hear a leak, tighten the clamps a bit more. A small leak will often seal itself as the metal expands with heat, but it's better to address it immediately.
  • Monitor for drone. If you experience excessive interior drone after installation, consider adding a resonator or a sound-deadening material like Dynamat in the cabin. Borla’s cat-back systems are designed to minimize drone, but individual results can vary.

It is important to understand the legal implications of modifying your exhaust system. In the United States, exhaust modifications are regulated by the Environmental Protection Agency (EPA) and often by state laws. Borla cat-back systems are generally considered legal because they do not alter the catalytic converter or emissions control systems. However, removing the catalytic converter or using a muffler that bypasses emissions equipment is illegal for street use in all 50 states.

The Borla ATAK, S-Type, and Touring cat-back systems are designed to be bolt-on replacements that maintain the factory catalytic converter placement. They are subject to local noise ordinances, so check your state’s decibel limits before choosing an ATAK if you live in a strict area like California or New York. The XR-1 race muffler is not street legal in many states and is intended for off-road or track use only.

If your Silverado is used for towing heavy loads, an aftermarket exhaust can help lower exhaust gas temperatures (EGT) and improve engine cooling. However, always monitor your truck’s performance after installation, as some aftermarket exhausts can alter backpressure enough to trigger check engine lights in certain model years. Installing a Borla system that includes all factory sensors and O2 ports will minimize this risk.

Maintaining Your Borla Exhaust

One of the reasons Borla is so highly regarded is the low maintenance required for their stainless steel systems. Unlike coated mild steel exhausts that can rust from the inside out, Borla’s 304 stainless steel resists corrosion and will last for the life of your truck. That said, you can keep it looking great with occasional cleaning. Use a mild soap and water solution with a soft cloth to remove dirt and road grime. Avoid harsh chemicals or abrasive pads that could scratch the polished tips. For a deep shine, apply a metal polish designed for stainless steel every few months.

Check the clamps and hangers every year or after severe off-road use. Borla uses high-quality T-bolt clamps that rarely loosen, but it’s a good practice to inspect them for tightness. If you notice any rattling against the underbody, check for debris caught between the exhaust and the frame, and adjust the rubber hangers as needed. Overall, a Borla exhaust should be a set-and-forget addition to your Silverado.

Final Thoughts: Which Borla Exhaust Is Right for You?

Choosing the best Borla exhaust system for your Chevy Silverado comes down to your personal preferences and how you use your truck. If you want the ultimate in power and sound and you don’t mind the volume, the ATAK is unmatched. If you want a sporty, aggressive tone that still works for daily driving and occasional towing, the S-Type is the ideal all-rounder. For those who prioritize cabin comfort and a subtle upgrade, the Touring system delivers. And if you are building a dedicated off-road or race truck, the XR-1 or Pro XS muffler can give you the sound and flow you need at a lower cost.

No matter which system you choose, Borla’s reputation for quality, performance, and durability means you are making a wise investment.
