You didn’t buy a 710-horsepower, supercharged 6.2L HEMI V8 to sound like a minivan. You bought the Dodge Durango SRT Hellcat because it’s the world’s most aggressive three-row SUV. It’s a track-ready monster that happens to have enough room for the kids, the dog, and the groceries.
But there’s a problem. From the factory, the exhaust is surprisingly tame. And if you go with the wrong aftermarket setup, you’ll trade that silence for a mind-numbing "drone" that makes long family road trips a living nightmare.
The mission is simple: More muscle. Zero drone.
At DTX Performance, we focus on high-performance parts that push your vehicle further without sacrificing the drive. If you want the best exhaust for the Durango SRT Hellcat that keeps the cabin quiet enough for a phone call but loud enough to wake the neighbors, you have two clear winners: Borla S-Type and AWE Touring Edition.
Why "Zero Drone" is the Only Metric That Matters
If this were a Challenger or a dedicated track build, drone might be a secondary concern. But the Durango Hellcat is a family hauler. "Drone" is that low-frequency hum that vibrates the interior panels at highway speeds (usually between 1,700 and 2,100 RPM). It’s the sound of a headache in the making.
To keep the peace in the backseat while maintaining the Hellcat’s authority, you need an exhaust system with specialized resonance technology.
1. Borla S-Type: The "No-Drone" Guarantee
Borla is an industry titan for a reason. Their S-Type Cat-Back system (Part #140885) is specifically engineered for the 2021-2026 Durango SRT Hellcat.
The Sound Profile
The S-Type is Borla’s "middle" ground, more aggressive than the Touring, but more refined than the rowdy ATAK. It delivers a crisp, snarling V8 bark when you floor it, but it settles into a deep, sophisticated hum at cruising speeds.
Key Performance Specs:
- Technology: Borla’s proprietary polyphonic harmonizers and T-304 stainless steel construction.
- The Vibe: Classic American Muscle. Higher-pitched and "raspy" at the top of the RPM range.
- Drone Control: Borla explicitly guarantees a drone-free experience on this exact platform.
- Tips: 4.5-inch or 5-inch round rolled-edge tips.

2. AWE Touring Edition: Precision Engineering with 180 Technology
If Borla is the classic choice, AWE is the precision-engineered alternative. The AWE Touring Edition Exhaust for the Durango Hellcat is a masterclass in sound management.
Patented 180 Technology®
AWE uses a patented "180 Technology" resonator. As exhaust gases enter the resonator, they are reflected back 180 degrees to cancel out specific drone-producing frequencies. It’s like noise-canceling headphones for your SUV.
The Sound Profile
AWE tends to produce a deeper, smoother, and "thumpier" sound compared to Borla. It sounds incredibly premium, like a high-end European performance car with an American heart.
Key Performance Specs:
- Performance Gains: Dyno-proven max gains of +10 hp and +4 lb-ft at the wheels.
- Weight Savings: Approximately 12 lbs lighter than the restrictive stock system.
- Construction: U.S.-made T304L stainless steel with a lifetime warranty.
- Tips: Massive 5-inch double-walled slash-cut tips in Chrome Silver or Diamond Black.

| Weight | Lighter than stock | 12 lbs Lighter than stock |
| Best For | The Classic Muscle Purist | The Modern Performance Techie |
Performance and Precision: Push Your Durango Further
Upgrading your exhaust isn't just about sound. The stock Durango Hellcat exhaust is heavy and restrictive. Both Borla and AWE utilize 3-inch mandrel-bent tubing to maximize flow. When you reduce backpressure, you allow the 2.4L supercharger to breathe, leading to better throttle response and more consistent power delivery.
Select Your Setup
- Choose Borla S-Type if you want that iconic, "crisp" Mopar sound that turns heads at every stoplight but remains silent on the highway.
- Choose AWE Touring if you want a deeper, more refined rumble and the peace of mind that comes with patented frequency-canceling technology.

FAQ: Durango SRT Hellcat Exhaust Upgrades
Q: Will these systems trigger a Check Engine Light (CEL)? A: No. Both the Borla S-Type and AWE Touring Edition are designed as direct bolt-on cat-back systems that do not interfere with emissions equipment.
Q: Can I install this myself? A: If you have a lift and basic tools, yes. However, due to the size and weight of the Durango system, we recommend professional installation to ensure perfect tip alignment and a leak-free seal.
Q: Do I need to buy gaskets separately? A: Most cat-back systems reuse the factory hardware or include the necessary clamps for installation. Always check the specific product listing for details. (Note: DTX Performance does not sell gaskets).
Q: Does it retain the Active Exhaust Valves? A: Most Borla systems for the Durango Hellcat are designed to work with the factory valve actuators. AWE systems often use a "simulated" bracket or bypass depending on the specific SKU. Check the part number before ordering.
