The C7 Corvette is a masterclass in American engineering. Whether you are piloting the naturally aspirated LT1 Stingray or the supercharged LT4 Z06, the platform is built for dominance. However, from the factory, the soul of the small-block V8 is often muffled. To truly unlock the visceral experience of the C7, an aftermarket exhaust is the first and most vital upgrade.
At DTX Performance, we don't just sell parts; we provide the hardware required to transform your driving experience. Choosing the right system means balancing volume, tone, and cabin comfort. This guide breaks down the three titans of the industry: AWE, Borla, and Corsa.
Push the limits. Build the sound. Select your system.
PUSH THE VOLUME: THE AWE PERFORMANCE LINEUP
AWE has rapidly become a favorite for C7 owners who want maximum impact. Their approach is simple: engineering excellence combined with raw, unapologetic sound. AWE offers two primary configurations for the C7 Corvette: the Touring Edition and the Track Edition.
UNLOCK THE TOURING EDITION
The Touring Edition is designed for the enthusiast who demands a Jekyll and Hyde personality. It utilizes AWE’s proprietary 180 Technology®. This isn't just a muffler; it’s a drone-canceling resonator tuned specifically to eliminate the frequencies that cause cabin resonance.
When you’re cruising at highway speeds, the 180 Technology® keeps the interior quiet and professional. When you drop a gear and bury the throttle, the system opens up to deliver a deep, muscular growl that command attention.
UNLOCK THE TRACK EDITION
If you live for the redline and want everyone within a three-block radius to know it, the Track Edition is your weapon of choice. This system deletes the 180 Technology® resonators, replacing them with straight pipes. It is the lightest and loudest option AWE offers.
On a C7 Grand Sport, AWE systems have been measured at a staggering 128.4 decibels. It is raw, raspy, and relentless. It’s the ultimate setup for a dedicated track car or a weekend warrior that refuses to be ignored.
BUILD THE TONE: THE BORLA THREE-TIER STRATEGY
Borla is a legacy name in the Corvette world. Their systems are built from aircraft-grade T-304 austenitic stainless steel, ensuring they will likely outlast the car itself. Borla’s strength lies in their three distinct "sound levels," allowing you to tailor the LT1 or LT4 note to your exact preference.
SELECT BORLA TOURING
The Borla Touring system is for the driver who wants a refined upgrade over the stock NPP system. It provides a deeper, more rounded tone without a massive increase in volume. It’s perfect for long-distance cruising and maintaining a "sleeper" status until you really lean into it.
SELECT BORLA S-TYPE
The S-Type is the "Goldilocks" of the Borla family. It offers a significantly more aggressive note than the Touring version, featuring a rich, bass-heavy idle and a crisp, clear bark under acceleration. It captures the classic American V8 rumble better than almost any other system on the market.
SELECT BORLA ATAK
ATAK stands for Acoustically Tuned Applied Kinetics. This is Borla’s most aggressive offering. Unlike the AWE Track edition which is just "loud," the ATAK is engineered to pump specific high-decibel frequencies into the air. It is high-pitched, raspy, and features a violent crackle on deceleration. If you want your Z06 to sound like a C7.R race car, this is the path to take.
DEFINE PRECISION: THE CORSA REFLECTIVE SOUND CANCELLATION
Corsa Performance is synonymous with "Exotic Sound." If Borla is a classic muscle car growl, Corsa is a high-frequency scream. Corsa systems are famous for their Reflective Sound Cancellation (RSC) technology, which was the first to truly solve the "drone" problem in high-performance Corvettes.
THE RSC ADVANTAGE
Corsa’s RSC technology targets and eliminates the low-frequency sound waves that cause interior drone. This allows them to build an exhaust that is incredibly loud on the outside while remaining virtually silent at a steady cruise. It is a no-compromise solution for the daily driver.
THE EXOTIC NOTE
Corsa systems, particularly the Xtreme Series, offer a unique tonal quality. They lean into the higher frequencies of the LT engine, resulting in a sound that mimics European supercars more than traditional American iron. It is clean, crisp, and devoid of "mushy" bass.
One critical note for C7 owners: Corsa systems typically disable the electronic valve control found in factory NPP systems. The valves are replaced with a mechanical design, meaning you lose the "Stealth Mode" functionality in exchange for consistent, high-performance flow.
COMPARE THE CONTENDERS: SIDE-BY-SIDE
Choosing between these three brands comes down to your personal "Sound Signature." As a premier performance car parts online destination, we see owners gravitate toward these systems for specific reasons:
| Feature | AWE | Borla | Corsa |
|---|---|---|---|
| Primary Tone | Deep / Raw | Muscular / Rich | Exotic / High-Pitch |
| Drone Control | 180 Technology | Multi-Core Mufflers | RSC Technology |
| Material | T-304 Stainless | T-304 Stainless | T-304 Stainless |
| Warranty | Lifetime (Structural) | Million-Mile | Lifetime |
| NPP Retention | No | Yes (Specific Models) | No |
THE DRONE FACTOR
Drone is the enemy of any Corvette build. There is nothing worse than a $100,000 Z06 that gives you a headache at 70 mph.
- Corsa is the undisputed king of zero-drone.
- AWE Touring is a close second with its resonance-canceling chambers.
- Borla manages drone well through traditional baffling, though the ATAK can still be "present" in the cabin during certain load conditions.
INSTALLATION AND BUILD QUALITY
All three brands utilize high-quality stainless steel, but Borla’s million-mile warranty is a massive confidence booster for long-term owners. When shopping at an automotive performance shop online, ensure you are looking at the specific fitment for your year. C7 Corvettes changed slightly throughout the production run (2014-2019), and Z06/ZR1 models require larger diameter piping to handle the forced induction flow of the LT4 and LT5.
THE X-PIPE FACTOR: DON'T SKIP THE MID-SECTION
If you are replacing your mufflers (axle-back), you are only doing half the job. To truly maximize the flow and sound of your C7, you need a high-flow X-pipe.
The factory mid-section contains secondary catalytic converters (on most models) and a restrictive "crush" section. Upgrading to a 3-inch X-pipe from AWE or Borla smooths out the exhaust pulses, adds roughly 10-15 horsepower, and significantly enhances the "pop and bang" on downshifts.
For those pushing high horsepower numbers on the track, remember that increased power generates increased heat. While you’re upgrading your airflow, consider your cooling system. High-performance builds often require upgraded radiators like the CSF 07-08 Nissan 350z 3.5L Radiator (though obviously, you'll want to find the Corvette-specific CSF model in our sitemap).
