1. Borla ATAK Cat-Back Exhaust System 140748: Best Overall Aggressive Sound
The Borla ATAK is engineered for maximum sound output, using a straight-through design and tuned resonators to produce an aggressive, race-inspired note. Owner feedback consistently praises its deep idle and explosive full-throttle roar, with minimal drone thanks to Borla’s Reflective Sound Cancellation technology. In our evaluation, the T304 stainless steel and precision welding indicate long-term durability.
However, the ATAK’s volume may be overwhelming for those seeking a subtle upgrade. It is best suited for enthusiasts who want an unmistakable presence and are willing to accept higher noise levels. Drivers sensitive to interior resonance should consider the Borla S-Type or a different brand.
- Aggressive, track-inspired tone with minimal drone at highway speeds
- Aerospace-grade stainless steel construction resists corrosion
- Direct-fit design with factory hangers for straightforward installation
Pros: Deep, loud roar that intensifies under throttle; Excellent build quality and lifetime warranty
Cons: Can be too loud for daily commuters or neighborhoods
2. MagnaFlow 19426 Cat-Back Exhaust System: Best Deep Tones
The MagnaFlow 19426 delivers a classic deep tone that RAM owners love, thanks to its large, free-flowing muffler and straight-through design. Based on owner feedback, the sound is noticeably deeper than stock but not obnoxious, with zero drone at cruising speeds. The 409 stainless steel is durable but less corrosion-resistant than T304, so it may not be ideal for harsh winter climates.
This system is a great value for those wanting a refined, aggressive sound without breaking the bank. However, if you live in the rust belt or demand the highest corrosion resistance, consider spending more on a T304 system. Installation is straightforward, though some users recommend a second set of hands for alignment.
- Rich, deep tone with moderate volume and no drone
- Lifetime warranty and 100% stainless steel construction
- Simple bolt-on installation with included hardware
Pros: Smooth, muscle-car rumble that is pleasant on highways; Affordable compared to premium brands
Cons: 409 stainless steel may show surface rust over time in salt states
3. Flowmaster Outlaw Cat-Back Exhaust System 817658: Loudest Straight-Through
The Flowmaster Outlaw is for those who want the loudest possible exhaust. It uses a straight-through design with minimal sound absorption, resulting in a raw, aggressive tone that is unmistakable. Owner feedback highlights its thunderous idle and ear-splitting acceleration, but many note significant interior drone between 1500-2000 RPM.
This system is best for off-road or weekend use where noise is welcomed. The aluminized steel is prone to corrosion in salted roads, so it is not recommended for daily drivers in snowy climates. If you prioritize a refined sound or need drone-free cruising, look elsewhere.
- Extremely loud, aggressive tone with no muffling
- Straight-through design maximizes exhaust flow
- Includes tailpipes and polished tips
Pros: Raw, unrestricted sound that turns heads; Bold appearance with dual tips
Cons: Aluminized steel can rust; not for salt-belt regions; Interior drone may be fatiguing on long trips
4. Corsa Performance Sport Cat-Back Exhaust 21264: Best No-Drone Technology
Corsa’s RSC (Reflective Sound Cancellation) technology sets this system apart, providing a loud exterior roar while keeping the cabin quiet. Owner reviews consistently praise the lack of drone, even at highway speeds, and the refined, aggressive tone. The T304 stainless steel construction ensures excellent corrosion resistance and longevity.
The main drawback is the premium cost, which may not fit all budgets. However, for those who want a loud exhaust without interior drone, the Corsa Sport is a top-tier choice. It is also one of the easier systems to install, with precise fitment reported by most users.
- Patented RSC technology eliminates drone without sacrificing volume
- Deep, aggressive sound with a crisp, exotic note
- Premium T304 stainless steel with CNC mandrel bends
Pros: Zero drone at any RPM, making it ideal for daily driving; High-quality materials and fitment
Cons: Higher price point than many competitors
5. MBRP S6224209 Cat-Back Exhaust System: Best Value
The MBRP S6224209 offers a solid balance of sound and affordability. Based on owner feedback, it produces a deep, mellow tone that is louder than stock but not overwhelming. The 409 stainless steel is durable but may develop surface rust over time in areas with road salt. Installation is straightforward, with all hardware included.
This system is ideal for budget-conscious buyers who want an improved sound without breaking the bank. However, if you demand maximum volume or the highest corrosion resistance, you may want to invest in a T304 system. It also lacks the aggressive edge of some competitors.
- Deep, mellow tone with moderate volume
- Affordable price with lifetime warranty
- Easy bolt-on installation with no cutting required
Pros: Great sound for the price; Simple, clean design
Cons: 409 stainless steel may rust in corrosive environments; Not as loud as premium systems
6. Gibson Performance Exhaust 31491 Single Side Exhaust: Best Mild Upgrade
The Gibson 31491 is designed for owners who want a modest improvement in sound without attracting attention. It produces a deeper tone than stock but remains relatively quiet, with no drone. The aluminized steel construction is lighter but less corrosion-resistant than stainless steel, making it best for dry climates.
This system is a good choice for daily drivers who want a slight rumble without the noise of a full cat-back. However, if you are seeking an aggressive exhaust note, this will likely disappoint. Installation is simple, and the polished tip adds a nice visual touch.
- Subtle, deep tone that is only slightly louder than stock
- Direct-fit with factory hangers for easy installation
- Includes polished stainless steel tip
Pros: Very affordable and easy to install; Good for those wanting a mild sound upgrade
Cons: Aluminized steel can rust; not for harsh climates; Sound may be too quiet for some enthusiasts
7. Rugged Ridge 11551.19 Cat-Back Exhaust System: Best Off-Road Sound
The Rugged Ridge system targets off-road enthusiasts who need a durable exhaust that can handle bumps and debris. It produces a deep, rumbling tone that is noticeable but not overly loud. However, the aluminized steel may not hold up well in wet or salty environments, and there is less owner feedback available compared to more popular brands.
This exhaust is best for those who primarily drive off-road and want a rugged, affordable option. It is not recommended for daily drivers or those seeking a refined sound. Installation is straightforward, but the fitment may require minor adjustments.
- Deep, rumbling tone suitable for off-road use
- Designed to withstand rough terrain with sturdy hangers
- Includes chrome-plated tips
Pros: Rugged build for off-road conditions; Aggressive sound at low RPM
Cons: Aluminized steel prone to rust; Limited owner feedback; less proven than competitors
Frequently Asked Questions
What is the loudest exhaust for a RAM 5.7 HEMI?
Based on owner feedback and spec comparisons, the Flowmaster Outlaw and Borla ATAK are the loudest options. The Flowmaster Outlaw uses a straight-through design with minimal sound deadening, while the Borla ATAK offers a more controlled aggressive tone. Both produce significant volume, but the Outlaw may have more interior drone.
Will a cat-back exhaust void my RAM's warranty?
No, a cat-back exhaust generally does not void the vehicle warranty under the Magnuson-Moss Warranty Act. However, if the exhaust causes damage to other components, the dealer may deny coverage for that specific issue. Always keep your original parts and consult your dealer if concerned.
How do I choose between single and dual exit exhaust?
Single exit systems are typically lighter and less expensive, while dual exit systems offer a more aggressive appearance and potentially slightly better flow. Sound differences are minimal; choose based on aesthetic preference and budget. For RAM trucks, dual exits are popular for a symmetrical look.
What is drone and how can I avoid it?
Drone is a low-frequency resonance that occurs at certain RPMs, often during highway cruising. To avoid it, choose systems with technology like Corsa’s RSC or Borla’s Reflective Sound Cancellation. Systems with Helmholtz resonators or large mufflers also reduce drone. Reading owner reviews can help identify drone-prone models.
Can I install a cat-back exhaust myself?
Yes, most cat-back exhausts are designed for bolt-on installation with basic hand tools. The process typically takes 1-3 hours. However, some systems may require cutting or welding if they are not direct-fit. Always follow the manufacturer’s instructions and consider a helper for alignment.
Our Verdict
After comparing specs, owner feedback, and industry standards, the Borla ATAK Cat-Back Exhaust System stands out as the top pick for its aggressive sound, quality construction, and minimal drone. For those prioritizing a no-drone experience with a refined tone, the Corsa Performance Sport is an excellent runner-up, offering similar volume without interior resonance.
