1. Borla Atak Cat-Back Exhaust System: Top Pick
In our evaluation, the Borla Atak Cat-Back Exhaust System delivers one of the loudest and most aggressive sounds on the market. Built from T-304 stainless steel, it offers excellent durability and corrosion resistance. Owner feedback consistently praises the deep, roaring tone that turns heads, though some note it may drone on the highway.
However, this system is not for everyone. Its extreme volume may violate noise ordinances in some areas, and the aggressive sound can be fatiguing on long trips. If you prioritize a civilized daily driver, skip this one. It is best suited for weekend warriors and track enthusiasts who want maximum volume.
- Multi-core straight-through muffler for maximum flow and volume
- T-304 stainless steel construction resists corrosion
- Includes all hardware and gaskets for bolt-on installation
Pros: Extremely loud with a deep, aggressive tone; High-quality materials and fitment
Cons: Can be too loud for daily driving
2. Flowmaster Outlaw Cat-Back Exhaust System: Best Value
After comparing owner feedback and spec sheets, the Flowmaster Outlaw Cat-Back stands out for its aggressive sound at a reasonable cost. Its chambered muffler produces a deep, gurgling idle and a loud roar under acceleration. The aluminized steel construction is durable but not as corrosion-resistant as stainless steel.
This system is ideal for budget-conscious buyers who want a loud exhaust without breaking the bank. However, if you live in a region with road salt or high humidity, consider upgrading to a stainless option to avoid premature rust. It may also be too loud for some neighborhoods.
- Chambered muffler design for a loud, aggressive sound
- Aluminized steel construction for moderate corrosion resistance
- Direct fit with mandrel-bent tubing
Pros: Very loud with a classic muscle car sound; Affordable compared to stainless steel systems
Cons: Aluminized steel may rust over time in harsh climates
3. MagnaFlow Street Series Cat-Back Exhaust: Balanced Performer
Based on our research, the MagnaFlow Street Series offers a well-rounded loud exhaust experience. It uses a straight-through design that produces a deep, aggressive tone without the extreme volume of some competitors. The T-304 stainless steel ensures long-term durability, even in harsh environments.
This system is a great choice for those who want a noticeable sound upgrade without overwhelming drone. However, if you are seeking the absolute loudest system for competitions or maximum attention, this may be too mild. It suits daily drivers who enjoy a sporty note.
- Straight-through perforated core muffler for smooth flow
- T-304 stainless steel for lifetime durability
- Deep tone without excessive drone
Pros: High-quality stainless steel build; Loud but not obnoxious, good for daily driving
Cons: Not the loudest option available
4. Corsa Performance Xtreme Cat-Back Exhaust: No Drone
In our evaluation, the Corsa Xtreme stands out for its unique RSC technology that cancels drone while maintaining a loud exterior roar. Owner feedback highlights the aggressive sound under acceleration and the near-stock interior noise at highway speeds. The T-304 stainless steel ensures long life.
However, the premium price may deter budget-conscious buyers. Additionally, some owners report fitment issues on certain models. If you want a loud exhaust without cabin drone and are willing to invest, this is an excellent choice. Skip it if you are on a tight budget or prefer a deeper, rumbling tone.
- Reflective Sound Cancellation (RSC) eliminates interior drone
- Loud exterior sound with a clean, crisp tone
- Mandrel-bent tubing for optimal flow
Pros: Very loud outside but quiet inside at cruise; Premium stainless steel construction
Cons: Higher price point
5. MBRP Armor Plus Cat-Back Exhaust: Affordable Loud
After comparing owner feedback, the MBRP Armor Plus delivers impressive loudness at an affordable price. The straight-through muffler produces a deep, aggressive sound that rivals more expensive systems. The aluminized steel with black ceramic coating offers moderate corrosion resistance.
However, durability is a concern in regions with road salt or high humidity, as the coating can wear over time. Some owners report fitment issues on certain vehicles. This system is ideal for those who want maximum loudness on a budget and live in dry climates. Avoid it if you need long-term corrosion resistance or a perfect fit.
- Straight-through muffler for maximum volume
- Aluminized steel construction with a black ceramic coating
- Includes band clamps for easy installation
Pros: Very loud with a deep tone; Budget-friendly price
Cons: Aluminized steel may rust in salt belt states
6. AWE Tuning Track Edition Cat-Back Exhaust: Track Ready
Based on our research, the AWE Tuning Track Edition is built for maximum volume and performance, targeting track enthusiasts. The straight-through design and T-304 stainless steel ensure durability and a raw, aggressive sound. Owner feedback notes that it is one of the loudest options available.
However, this system is not suitable for daily driving due to extreme drone and volume that may attract unwanted attention. Fitment is limited to specific models, and the price is high for the features. Skip this if you need a street-friendly exhaust; it is best for dedicated track cars.
- Straight-through design for maximum flow and volume
- T-304 stainless steel with a brushed finish
- Dual rear exits for an aggressive look
Pros: Extremely loud, ideal for track use; High-quality stainless steel
Cons: Very loud for street driving, may cause drone; Limited vehicle fitment
7. Gibson Performance Cat-Back Exhaust System: Deep Tone
In our evaluation, the Gibson Performance Cat-Back offers a deep, rumbling tone that appeals to classic muscle car fans. The chambered muffler produces a mellow sound that is loud but not obnoxious. The aluminized steel with ceramic coating provides decent corrosion resistance for the price.
However, this system is quieter than many competitors, so it may not satisfy those seeking maximum volume. Some owners report that the sound becomes raspy at high RPM. It is a good choice for drivers who want a deep, old-school rumble without excessive noise. Skip it if you want the loudest exhaust possible.
- Chambered muffler for a deep, mellow rumble
- Aluminized steel with a silver ceramic coating
- Mandrel-bent tubing for smooth flow
Pros: Deep, muscle car tone; Easy bolt-on installation
Cons: Not as loud as straight-through designs; Aluminized steel may corrode over time
Frequently Asked Questions
What is the loudest exhaust system for a car?
Based on our research, the Borla Atak and AWE Tuning Track Edition are among the loudest exhaust systems available. The Borla Atak offers a deep, aggressive roar, while the AWE Tuning Track Edition is designed for track use with extreme volume. Owner feedback indicates both produce significant sound levels that may exceed legal limits in some areas.
Will a loud exhaust void my car's warranty?
An aftermarket exhaust generally does not void the entire warranty, but it may affect coverage for related components. The Magnuson-Moss Warranty Act protects consumers, but manufacturers can deny claims if they prove the exhaust caused the damage. We recommend checking your vehicle’s warranty terms before installation.
How do I choose between aluminized steel and stainless steel exhaust?
Stainless steel (especially T-304) offers superior corrosion resistance and longevity, making it ideal for harsh climates. Aluminized steel is more affordable but may rust over time, especially in salt belt regions. For a loud exhaust that lasts, stainless steel is the better investment based on owner feedback.
Can a loud exhaust improve performance?
A loud exhaust may free up restrictions in the stock system, potentially increasing horsepower and torque by a modest amount. However, gains are usually small (5-15 hp) and depend on the vehicle. The primary benefit is sound rather than significant performance improvement.
Are loud exhausts legal on public roads?
Noise regulations vary by state and locality. Many areas have decibel limits, and excessively loud exhausts can result in fines or failed inspections. We recommend checking local laws before purchasing. Some systems like the Corsa Xtreme offer a loud exterior with minimal drone to help avoid attention.
Our Verdict
After researching and comparing the top options, our top pick is the Borla Atak Cat-Back Exhaust System for its exceptional loudness, build quality, and owner satisfaction. The runner-up is the Flowmaster Outlaw Cat-Back, offering a great balance of volume and value for budget-conscious buyers. Both deliver aggressive sound, but the Borla edges ahead with superior materials and a more refined tone.
