4 Best Borla Silverado Mufflers of 2026

The BORLA ATAK exhaust system unleashes a deep, aggressive muscle-car roar that turns heads before you even hit the gas. With its dual split rear exit design and T-304 stainless steel construction, this cat-back system delivers both jaw-dropping aesthetics and serious acoustic authority. Engineered specifically for the V8 Silverado and Sierra platforms, it maximizes exhaust flow through mandrel-bent tubing and a free-flowing straight-through ATAK muffler, eliminating bottlenecks and enhancing throttle response. If you crave a commanding presence and track-inspired sound without sacrificing daily drivability, this system answers the call.

On the road, the 140775 shines brightest under hard acceleration, where the exhaust note builds into a thunderous crescendo that’s rich in low-end growl and high-rpm snarl. During real-world testing, it maintained a refined tone at cruising speeds—thanks to BORLA’s patented internal tuning—while staying true to its no drone guarantee, keeping cabin resonance at bay on long highway stretches. The system fits snugly with bolt-on precision, reusing factory hangers and tips for a clean OEM+ look. While it doesn’t add massive horsepower on its own, it unlocks the engine’s true sonic potential and pairs perfectly with performance tune upgrades.

Compared to the S-Type variants in the BORLA lineup, the 140775 takes a far more aggressive stance—sonically and visually—making it ideal for drivers who want their Silverado to sound as powerful as it performs. It’s the top-tier choice for enthusiasts prioritizing maximum auditory impact over subtlety, especially when stacked against the milder S-Type models. Though heavier than some aftermarket alternatives due to its all-welded stainless build, the trade-off is unmatched durability and corrosion resistance. For those seeking the ultimate fusion of American muscle tone and precision engineering, the ATAK system outperforms the S-Type in sound intensity and presence, even if it commands a premium in both attention and installation care.

The BORLA S-Type 140769 strikes a masterful balance between sophistication and muscle, offering a sporty exhaust note that’s bold without being obnoxious. Built from austenitic T-304 stainless steel, this cat-back system features mandrel-bent tubing and a compact S-Type muffler tuned to deliver a throaty burble on start-up and a refined snarl under load. Its dual split rear exit layout maintains a clean, factory-like appearance while significantly upgrading both sound and exhaust efficiency. For Silverado owners who want a performance edge without drawing unwanted attention at stoplights, this system hits the sweet spot.

In daily driving scenarios, the 140769 impresses with its smooth tonal transition from idle to wide-open throttle—never harsh, always engaging. The exhaust enhances the V8’s natural rhythm, adding crisp crackles on downshifts while maintaining a comfortable cabin environment, backed by BORLA’s no drone guarantee. Installation is straightforward, leveraging factory mounting points and allowing reuse of OEM tips for a seamless integration. While it doesn’t reach the sonic extremes of the ATAK model, it excels in versatility, making it perfect for commuters who also enjoy weekend canyon runs or towing with style.

When compared to the ATAK 140775, the 140769 trades raw volume for tonal refinement, making it a smarter pick for drivers who value long-haul comfort alongside performance character. It’s also a direct competitor to the 140773, but with a more polished sound profile and slightly better build consistency. The S-Type doesn’t shout, but it commands respect—ideal for professionals or enthusiasts who want their truck to feel upgraded without feeling over-the-top. With the same Made in USA craftsmanship and corrosion-resistant materials as its louder sibling, it delivers a more balanced experience, offering richer sound and better flow than stock, but with far greater social acceptability.

For Silverado 6.2L V8 owners already running a BORLA cat-back system, the 60679 ATAK replacement muffler is the ultimate sonic upgrade—delivering the full, unfiltered roar of BORLA’s most aggressive tuning. Designed specifically as a direct-fit muffler swap, it maintains the integrity of your existing exhaust setup while transforming its voice into something far more menacing. Constructed from T-304 stainless steel with a straight-through multi-core design, this muffler maximizes exhaust velocity and eliminates restrictions, making it a favorite among performance tuners and track-focused truck owners.

Real-world testing confirms that the 60679 wakes up the LT1/L87 engines like nothing else—producing a deep, chest-thumping idle and a high-rpm scream that echoes true supercar DNA. It pairs exceptionally well with cold air intakes and performance tunes, where the increased airflow lets the muffler breathe fully and sing at its peak. Unlike universal-fit mufflers, this unit ensures perfect alignment and flow continuity, avoiding the performance dips common with cut-and-weld modifications. However, due to its extreme sound output, it’s best suited for weekend drivers or modified trucks where cabin quietness isn’t the priority.

Compared to full cat-back systems, the 60679 isn’t a standalone solution—it’s a targeted enhancement for those who already love their BORLA setup but crave more drama. It outperforms generic aftermarket mufflers in both durability and sound quality, thanks to BORLA’s proprietary acoustic engineering. While the full ATAK cat-back (like the 140775) offers a complete system upgrade, this muffler gives you the same iconic sound in a modular format. Ideal for enthusiasts who want to fine-tune their exhaust character without replacing the entire system, it’s the most focused way to amplify your Silverado’s presence—offering maximum sonic return on investment.

The BORLA 140773 stands out as the smart choice for Silverado and Sierra owners who want premium performance and sound without the premium price tag. Utilizing the same T-304 stainless steel and all-welded construction as its more expensive siblings, this S-Type system delivers a rich, sporty exhaust note with a subtle growl that elevates the driving experience without overwhelming it. Its dual split rear exit design maintains a clean, understated look while improving exhaust efficiency and throttle response—making it a true upgrade over stock in both form and function.

On the road, the 140773 performs admirably in mixed driving conditions, offering a noticeable improvement in engine character during acceleration while staying quiet and composed during cruise. The S-Type muffler tuning ensures a balanced tone—more engaging than factory, less intrusive than the ATAK—ideal for drivers who tow, commute, or simply prefer a refined growl. Installation is tool-friendly and follows BORLA’s bolt-on standard, reusing factory hangers and tips for a clean finish. While it doesn’t offer the deepest bass or crackle of the ATAK line, it delivers 90% of the experience at a more accessible point in the lineup.

Stacked against the 140769 S-Type, the 140773 is nearly identical in sound and construction, but often available at a more competitive entry point, earning its “Best Value” title. It doesn’t cut corners on materials or craftsmanship—still proudly Made in USA with the same corrosion-resistant steel and no drone promise. For first-time exhaust upgraders or budget-conscious enthusiasts who don’t want to compromise on brand integrity, this system offers the perfect blend of trust, tone, and affordability. While it may not turn as many heads as the ATAK, it delivers a satisfying upgrade over stock that feels both meaningful and lasting—proving you don’t need the loudest system to feel the difference.
