The 5.7L HEMI in the Dodge Durango R/T has a great voice hiding behind a quiet factory muffler, and the right exhaust system wakes it up without turning your daily driver into a headache. We focused on cat-back and axle-back kits that physically bolt to the Durango R/T, looking at tone, drone on the highway, weld and tubing quality, and how realistic the install is in a home garage.
Every system below is a real product available on Amazon that fits the 2011 and newer Durango R/T with the 5.7 HEMI. We ranked them by how aggressive yet livable the sound is, build materials, and how confident we are in the fitment and long term durability. No matter your budget, there is an option here that adds growl, frees up a little flow, and keeps cabin drone in check.

1. Borla S-Type Cat-Back Exhaust System (Dodge Durango R/T 5.7L): Best Overall
The Borla S-Type is our top pick for the Durango R/T because it nails the balance every HEMI owner actually wants. The straight-through S-Type muffler gives the 5.7 a deep, throaty growl under acceleration and a confident burble at idle, yet it settles down enough at a steady 70 mph that you can hold a phone call without shouting. The full T-304 stainless construction is a clear step above the aluminized systems some rivals use, and the mandrel bent tubing keeps flow smooth from the mid pipe back to the polished tips.
Fitment is genuinely bolt-on and reuses the factory hanger locations, so most owners finish the job in an afternoon with hand tools and a couple of jack stands. The honest weakness is alignment at the rear: the tips can sit slightly uneven in the bumper cutouts if you rush the clamp positioning, so plan to loosen everything, level the tips, then torque it all down. It is also a touch louder on a cold start than a quiet daily driver might want, but once warm it mellows into exactly the tone the Durango R/T should have left the factory with.
- Patented straight-through S-Type muffler tuning for aggressive but controlled tone
- Full T-304 stainless steel tubing and mandrel bends for long term corrosion resistance
- Bolt-on cat-back design that mates to factory hangers and exhaust flanges
Pros: Deep, refined HEMI growl that stays clean under hard throttle; Premium T-304 stainless build with excellent welds and polished tips; Minimal cabin drone at highway cruise for a daily driver
Cons: Tips and clamps need careful alignment to sit evenly in the fascia; Sound is louder than some owners expect on cold starts
2. Flowmaster American Thunder Cat-Back Exhaust (Durango 5.7L HEMI): Best Aggressive Sound
If you want your Durango R/T to announce itself, the Flowmaster American Thunder system delivers that classic American muscle tone better than almost anything else on this list. Flowmaster built its name on chambered mufflers, and this kit channels that heritage into a deep, aggressive rumble that sounds fantastic when you bury the throttle. The 409 stainless tubing with mandrel bends is plenty durable for a daily truck that sees winter roads, and the throttle response feels a little sharper thanks to the freer flowing path.
The trade off is volume and drone. This is one of the louder systems here, and at certain highway cruising speeds you will notice a resonant hum inside the cabin that some drivers love and others find tiring on a long trip. If you commute long distances every day, that drone is worth weighing seriously. But for owners who want raw character and do not mind the neighbors knowing the HEMI is awake, the American Thunder is exactly what the badge promises.
- Flowmaster chambered muffler technology tuned for a deep, aggressive HEMI rumble
- Mandrel bent 409 stainless tubing for durability and consistent flow
- Direct fit cat-back kit with included clamps and hardware
Pros: Loud, unmistakable Flowmaster muscle car tone; Durable 409 stainless tubing holds up to road salt and weather; Noticeable throttle response improvement off the line
Cons: Can produce noticeable highway drone for sensitive drivers; More aggressive volume than buyers wanting a subtle upgrade may like
3. MagnaFlow Street Series Cat-Back Exhaust (Dodge Durango 5.7L): Best Build Quality
MagnaFlow has a reputation for some of the cleanest stainless work in the aftermarket, and the Street Series for the Durango lives up to it. Everything from the perforated straight-through core to the mandrel bent T-304 tubing feels overbuilt, and the welds are tidy enough that you will not mind people looking under the truck. The tone is a deep, smooth note that adds presence without the metallic rasp that cheaper systems can produce, which makes it a great choice if you want sound quality over raw decibels.
The fitment is a true bolt-on that reuses factory hanger points, so the install is approachable for a weekend mechanic. The honest weakness is that this is a refined system rather than a rowdy one, so if your goal is to be the loudest Durango at the meet, you may find it more reserved than you hoped. The polished tips also reward a little maintenance, since they can show water spotting if you never wipe them down. For owners prioritizing build quality and a mature tone, this is the system to beat.
- Straight-through perforated core muffler for smooth flow and a refined tone
- Premium T-304 stainless steel throughout for maximum corrosion resistance
- Precision mandrel bends and a fully bolt-on, no weld installation
Pros: Outstanding T-304 stainless fit and finish; Smooth, deep tone without harsh rasp; Easy bolt-on install with excellent fitment
Cons: More subdued than buyers chasing maximum loudness expect; Tips finish can show water spotting without occasional cleaning
4. Corsa Performance Sport Cat-Back Exhaust (Durango R/T 5.7L HEMI): Best No-Drone Daily Driver
Corsa built its whole reputation on solving the one problem that ruins many exhaust upgrades: drone. The Sport cat-back for the Durango R/T uses Corsa’s Reflective Sound Cancellation technology to keep the cabin quiet at steady highway speeds while still letting the 5.7 HEMI roar when you get into the throttle. The result is a system that feels almost two-faced in the best way, aggressive when you want it and calm when you do not, which is exactly what a daily driven family SUV needs.
The T-304 stainless build is excellent and the bolt-on fitment is straightforward, reusing the factory hangers. The main thing to weigh is value, since Corsa sits at the premium end of the market and you are paying for that drone-canceling engineering. It is also a bit more reserved at idle than a chambered Flowmaster, so if you crave a loud cold start, this is not the one. But for road trip comfort with real performance character on tap, the Corsa Sport is hard to beat.
- Patented Reflective Sound Cancellation technology eliminates highway drone
- Aggressive tone under acceleration that quiets to a whisper at cruise
- Full T-304 stainless construction with a bolt-on, no weld design
Pros: Virtually zero cabin drone thanks to RSC technology; Aggressive on demand but calm at steady cruise; Premium T-304 stainless build and clean welds
Cons: Premium positioning means it sits at the higher end for value; Less raw volume at idle than chambered muffler systems
5. AWE Touring Edition Cat-Back Exhaust (Dodge Durango 5.7L): Best Balanced Tone
AWE makes some of the best looking and best engineered exhaust hardware in the business, and the Touring Edition for the Durango is tuned for owners who want a balanced, grown-up tone rather than maximum shock value. The proprietary resonator tuning gives the HEMI a satisfying low growl under load while keeping cabin drone well controlled, and AWE’s signature tips include a 180 degree internal design that helps keep the chrome from blackening with soot over time. The T-304 stainless construction and weld quality are genuinely impressive in person.
Installation is a bolt-on job using factory hanger locations, so a confident DIYer can manage it at home. The honest caveats are styling and price. The quad tip look is bold and not everyone loves it on a Durango, so check the fitment photos against your fascia before ordering. AWE also commands a premium, and you are paying for the brand and the finish. If those fit your priorities, this system rewards you with a refined tone and hardware that looks like jewelry under the rear bumper.
- AWE proprietary resonator tuning balances volume with low drone
- 180 degree tip option resists exhaust soot buildup on the chrome
- Full T-304 stainless tubing with mandrel bends and precision welds
Pros: Balanced tone that is loud enough without being obnoxious; Beautiful tip and weld finish quality; Engineered drone suppression for comfortable cruising
Cons: Quad tip styling is not to every owner's taste; Premium pricing tier for the brand name
6. Flowmaster FlowFX Axle-Back Exhaust (Durango 5.7L HEMI): Best Easy Install
Not everyone wants to drop a full cat-back system, and the Flowmaster FlowFX axle-back is the smart pick for owners who want a meaningful sound upgrade with the least amount of wrenching. Because it only replaces the rear section behind the axle, the install is the easiest on this list and many owners finish it in under an hour with basic hand tools. The straight-through FlowFX muffler gives the Durango R/T a noticeably more aggressive note, and the 409 stainless build handles weather and road salt without complaint.
The trade off is inherent to the axle-back format. Since you are not changing the mid pipe or muffler section ahead of the axle, the tone change is moderate rather than transformative, and you will not see the flow benefits a full cat-back can offer. If you want the biggest possible difference, step up to one of the cat-back systems above. But if you want a quick, durable, budget-friendly way to free up the HEMI’s voice, the FlowFX axle-back punches above its weight.
- Axle-back design swaps only the rear section for a quick install
- Straight-through FlowFX muffler for a moderate, aggressive tone
- 409 stainless tubing and polished tips for weather resistance
Pros: Simplest install of any system here, often under an hour; Adds real HEMI growl without going overboard; Durable 409 stainless construction
Cons: Axle-back changes less than a full cat-back system; Tone gain is moderate rather than dramatic
7. Gibson Performance Cat-Back Exhaust System (Dodge Durango 5.7L): Best Value
Gibson has long been a go to for truck and SUV owners who want a complete, durable cat-back without paying the premium brand tax, and its Durango system continues that tradition. The Superflow muffler is tuned for a deep, mellow tone that sounds great at part throttle and never gets harsh or raspy, which makes it an easy system to live with day to day. The stainless tubing and mandrel bends give it solid durability, and the kit arrives complete with the hangers, clamps, and slash-cut tip you need to finish the job.
The compromises are mostly about style and character. The single side exit gives the Durango more of a traditional truck look than the dual or quad tip setups of pricier systems, so if you want a symmetrical sporty rear, this is not it. The tone also leans mellow rather than aggressive, which is a plus for some buyers and a minus for others. For owners who want a real stainless cat-back with everything included and dependable Gibson sound, the value here is genuinely hard to argue with.
- Gibson Superflow muffler tuned for a deep, mellow HEMI tone
- Stainless steel tubing with mandrel bends for solid durability
- Complete cat-back kit with hangers, clamps, and slash-cut tip included
Pros: Strong value for a complete stainless cat-back kit; Deep, mellow tone with minimal harshness; Everything needed for install comes in the box
Cons: Single side exit look is more truck than sport SUV; Tone is mellower and less aggressive than premium rivals
Frequently Asked Questions
Will a cat-back exhaust fit my Dodge Durango R/T without modifications?
Yes. Every system in this guide is designed as a direct, bolt-on fit for the Durango R/T with the 5.7L HEMI, and they reuse the factory hanger locations and connect to the stock mid pipe or axle flange. No cutting or welding is required for these cat-back and axle-back kits. The most important thing is to confirm your exact model year against the listing, since the Durango has spanned several generations, and to double check whether your kit is single or dual exit so the tips line up correctly with your rear fascia.
What is the difference between a cat-back and an axle-back exhaust on the Durango?
A cat-back system replaces everything from the catalytic converters back, including the mid pipe, muffler, and tips, while an axle-back only replaces the section behind the rear axle. Cat-back systems generally produce a bigger change in sound and can offer slightly more flow, but they cost more and take longer to install. An axle-back, like the Flowmaster FlowFX on this list, is far quicker to bolt on and still adds real HEMI growl, just with a more moderate change overall. Choose based on how dramatic a result you want versus how much work you want to do.
Will an aftermarket exhaust cause drone inside the Durango cabin?
It depends heavily on the system. Chambered muffler designs, like the Flowmaster American Thunder, tend to produce more noticeable highway drone, which is a resonant hum at steady cruising speeds. Systems engineered specifically to fight drone, such as the Corsa Sport with Reflective Sound Cancellation and the AWE Touring Edition, keep the cabin quiet on the highway while still sounding aggressive under throttle. If you drive long distances daily, prioritize a drone-controlled system. If you mostly want character around town, a chambered design will sound great and the drone matters less.
Does a new exhaust add horsepower to the 5.7 HEMI Durango R/T?
A cat-back or axle-back exhaust on its own typically adds a modest amount of power and torque rather than a dramatic gain, since the factory catalytic converters and tuning remain in place. The bigger benefits you will actually feel and hear are improved exhaust tone and slightly crisper throttle response from the freer flowing tubing. To see larger horsepower numbers you would generally pair the exhaust with intake, headers, and a custom tune. Think of these systems mainly as a sound and character upgrade with a small performance bonus.
Are these exhaust systems legal for street use?
The cat-back and axle-back systems in this guide sit behind the catalytic converters, so they do not remove any emissions equipment and are generally street legal in most areas. That said, noise ordinances vary by state and locality, and a few of the louder chambered systems could draw attention where strict sound limits apply. None of these kits delete catalytic converters, which is the part that matters most for emissions compliance. Always check your local regulations before purchasing, especially if you live somewhere with vehicle inspections or aggressive noise enforcement.
Our Verdict
For most Durango R/T owners, the Borla S-Type Cat-Back is our top pick because it nails the balance of an aggressive HEMI growl, premium T-304 stainless build, and livable highway manners, all in a true bolt-on package. If your priority is keeping the cabin quiet on long drives without giving up character, the Corsa Sport Cat-Back is our runner up thanks to its excellent drone-canceling engineering. Either way, you are giving the 5.7 HEMI the voice Dodge should have shipped from the factory.
