More Details on Our Top Picks
Borla 140585 Cat-Back Performance Exhaust System for 2015-2023 Ford Mustang
This Borla system stands out for its durable T-304 stainless steel construction and all-welded, bolt-on design, making it a reliable choice for Mustang owners seeking a straightforward upgrade. Compared with the MBRP S7200AL, it offers a more refined, drone-free ATAK sound that enhances performance without sacrificing comfort. The dual split rear exit and chrome tips give it a sleek appearance, while the all-welded build ensures longevity. However, the absence of specific pricing information and potential need for professional installation can add to the overall cost and complexity. This pick makes the most sense for enthusiasts who want a high-quality, hassle-free upgrade that balances aggressive sound with durability.
Pros:- Durable T-304 stainless steel construction ensures longevity
- All-welded, bolt-on design simplifies installation
- ATAK sound delivers aggressive performance without drone
Cons:- No specific price details available, potentially higher cost
- May require professional installation for perfect fit

- Material:T-304 stainless steel
- Installation:Bolt-on

Our verdict“This system is ideal for Mustang owners seeking a durable, high-performance exhaust with a refined, drone-free sound.”
MBRP S7200AL Dual Mufflers Axle Back Split Rear Exhaust System
This MBRP axle-back system delivers a notably deep and aggressive exhaust note, making it ideal for Mustang owners who want a commanding sound. Unlike the Borla, which emphasizes a refined tone, the S7200AL emphasizes raw power, complemented by sporty exhaust tips that enhance visual appeal. Its aluminized steel construction offers good corrosion resistance for the price, but installation may require more mechanical skill due to its complexity. The increased noise level and aggressive tone might be too much for daily drivers or those seeking a more subtle upgrade. If you prioritize a loud, sporty exhaust that enhances acceleration, this system fits well, though it trades off some refinement and ease of installation.
Pros:- Deep, aggressive exhaust tone for a powerful sound
- Corrosion and rust resistant aluminized steel
- Enhances vehicle appearance with sporty tips
- Improves acceleration and overall performance
Cons:- Installation may be technically challenging
- Noise levels could be excessive for some users
Best for: Owners who want an aggressive, loud exhaust that boosts performance and visual appeal.
Not ideal for: Daily drivers or those sensitive to increased cabin noise and drone.
- Material:Aluminized Steel
- Type:Axle Back Exhaust System
- Configuration:Dual Mufflers, Split Rear
Our verdict“This exhaust system suits Mustang owners seeking a bold, aggressive sound with performance gains, but may challenge daily comfort and installation skills.”
SLP LoudMouth Exhaust System for 1999-2004 Mustang GT / Mach 1
The SLP LoudMouth stands apart for its raw, aggressive sound and show-quality polished resonators, making it a favorite among enthusiasts of the older Mustang models like the 1999-2004 GT and Mach 1. Compared to the Borla 140585, which focuses on refined performance and drone-free operation, the LoudMouth offers a more visceral, attention-grabbing tone. Its resonators add aesthetic appeal, but the extreme sound level may be overwhelming for everyday use or neighbors. Installation can be complex, especially with the resonators, but the performance results are well-proven through dyno testing. This system is best for owners who want a loud, aggressive exhaust that makes a visual statement and enhances show car appeal.
Pros:- Provides an extremely loud, aggressive exhaust tone
- Includes show-quality polished resonators
- Dyno-proven to outperform many competitors
- Great visual appeal with double-wall tips
Cons:- May be too loud for daily driving or neighborhood use
- Installation can be complex and time-consuming
Best for: Owners of older Mustang models seeking a loud, performance-oriented exhaust with show-quality finish.
Not ideal for: Daily drivers or those seeking a quieter, more refined exhaust experience.
- Fits:1999-2004 Mustang GT / Mach 1
- Resonators:Loud Mouth resonators
- Tips:3.5 inch double-wall
Our verdict“Best suited for vintage Mustang owners who want a loud, show-stopping exhaust with proven performance gains, though it may be overkill for everyday driving.”
BORLA 11751 Axle-Back Performance Exhaust System for 2005-2009 Ford Mustang 4.0L V6
This Borla axle-back system is tailored for V6 Mustang models from 2005-2009, emphasizing a reliable, classic Borla sound with all-welded durability. Compared with the Borla 140585 for newer models, this version offers a more subdued but still sporty tone, ideal for owners who want performance without excessive noise. The stainless steel build ensures long life, but its limited compatibility means it won’t fit V8 models or newer Mustangs. The installation process is straightforward, making it a good choice for those upgrading their V6. However, owners seeking maximum sound or performance should look elsewhere, as this system prioritizes a smooth, refined V6 experience over aggressive tone.
Pros:- Durable stainless steel construction
- Easy bolt-on installation
- Produces a classic Borla sound
Cons:- Limited to V6 models only
- May not satisfy owners seeking aggressive sound or performance
Best for: V6 Mustang owners who want a dependable, classic Borla sound and easy installation.
Not ideal for: V8 Mustang owners or those looking for a loud, aggressive exhaust upgrade.
- Material:T-304 Stainless Steel
- Installation:Bolt-on
- Construction:All welded
- Compatibility:2005-2009 Ford Mustang 4.0L V6
Our verdict“This exhaust suits V6 Mustang owners wanting a reliable, refined Borla sound with straightforward installation.”
Auto Dynasty 4-Inch Axle-Back Catback Exhaust System for 2005-2010 Ford Mustang 4.6L & 5.4L
This Auto Dynasty system emphasizes performance gains, with increased horsepower and improved exhaust flow, making it well-suited for V8 Mustang owners seeking measurable power boosts. Its high-quality T-304 stainless steel and 2.5-inch piping compare favorably with the aluminized steel of the MBRP, offering better durability over time. The bolt-on design simplifies installation, but because it’s specifically tailored for 2005-2010 models with 4.6L or 5.4L engines, compatibility is limited. While the sound is improved, it’s not as aggressive as the SLP LoudMouth, making it a more balanced choice for performance-minded owners who prefer a moderate exhaust tone. Overall, this system provides meaningful performance improvements but requires considering other modifications for maximum effect.
Pros:- Increases horsepower and torque
- High-quality T-304 stainless steel construction
- Easy bolt-on installation with hardware included
- Enhances sound and performance
Cons:- Limited compatibility to specific models
- Performance gains vary with other modifications

- Engine Compatibility:4.6L, 5.4L
- Muffler/Exhaust Tip:4″ OD
- Major Piping:2.5″ OD
- Material:T-304 stainless steel
- Tip Shape:Round Diagonal Cut Rolled Lip
- Inlet / Outlet:2.5″ OD
Our verdict“This system is best for V8 Mustang owners aiming for horsepower gains and improved exhaust flow with moderate sound enhancement.”
DNA Motoring Cat Back Exhaust System for 2005-2010 Ford Mustang 4.6L / 5.4L
This DNA Motoring system stands out for its combination of high-quality materials and impressive performance gains. Made from T-304 stainless steel with mandrel bends, it offers a significant increase in horsepower and torque compared to stock setups, rivaling premium options like Borla but at a more affordable price. Its aggressive, deep exhaust tone appeals to enthusiasts seeking a bold sound, though the louder output might be too much for some daily drivers. Installation is straightforward for those with mechanical skills, but it can be challenging without proper tools. Compared to simpler bolt-on systems, this setup provides a noticeable performance boost and durability. However, the amplified exhaust note may be disruptive in residential areas, and the installation complexity could deter casual DIYers.
Pros:- Constructed from durable T-304 stainless steel with mandrel bends for optimal flow
- Instantly increases horsepower and torque
- Produces a deep, aggressive exhaust tone
Cons:- Installation may require technical skills and tools
- Louder sound might be too aggressive for some drivers
Best for: Performance-minded Mustang owners seeking increased power and a aggressive sound without a hefty price tag
Not ideal for: Casual drivers who prefer a quieter, more refined exhaust tone or lack mechanical experience
- Fitment:2005-2010 Ford Mustang 4.6L / 5.4L

- Construction:Mandrel-Bent, TIG welded CNC flange
- Inlet Diameter:3 inches
- Main Piping Diameter:3 inches

Our verdict“This system is ideal for enthusiasts wanting a robust upgrade that boosts performance and sound, provided they are comfortable with installation complexity.”
DNA Motoring CBE-FM05-46GT Cat Back Exhaust System for 2005-2010 Ford Mustang V6
This DNA Motoring V6-specific system emphasizes performance gains with its 3-inch mandrel-bent stainless steel pipes and dual 2.5-inch tailpipes, making it a solid upgrade over stock exhausts. Its design boosts horsepower and torque by up to 25%, similar to more expensive systems like Borla but tailored specifically for V6 models. The aggressive tone complements the increased flow, though installation may require some mechanical skill, especially for those unfamiliar with exhaust work. Compared to the 4.6L systems, it targets a different audience with a focus on V6 characteristics, meaning it might not fit other Mustang variants. Its durability and performance improvements make it a worthwhile upgrade, but the sound might be too loud for urban commuting or those seeking a milder exhaust note.
Pros:- Increases horsepower and torque by 15-25%
- High-quality T-304 stainless steel construction
- Aggressive, deep exhaust tone
Cons:- Requires mechanical skill for installation
- Designed exclusively for V6 models, limiting compatibility

- Material:T-304 Stainless Steel
- Construction:Mandrel-Bent, TIG welded CNC flange
- Piping Diameter:3 inches

Borla 11750 Axle-Back Performance Exhaust System for 2005-2009 Ford Mustang GT and Shelby GT500
This Borla axle-back system excels in ease of installation and consistent performance gains. Crafted from T-304 stainless steel, it offers a straightforward bolt-on process, making it an appealing choice for those who want a quick upgrade without custom fabrication. Compared to full cat-back systems like DNA Motoring, Borla’s design emphasizes durability and a signature sound that’s both aggressive and refined, with no drone at highway speeds. Its specific fit for GT and Shelby GT500 models ensures perfect compatibility, but this focus can limit its versatility for other Mustang variants. While it enhances power and torque noticeably, the higher price point might be a deterrent for budget-conscious buyers. Nonetheless, it’s a reliable, durable upgrade for performance-focused owners who prioritize ease of installation.
Pros:- Durable T-304 stainless steel construction
- Easy bolt-on installation
- Enhances power and torque with a signature Borla sound
Cons:- Designed specifically for certain models, limiting versatility
- Higher cost compared to generic systems
Best for: Mustang owners seeking a performance boost with minimal installation hassle and a distinctive Borla sound

Compared with newer systems, it provides a substantial power boost and improved exhaust flow while maintaining a relatively lightweight profile at 40 pounds, making it easier to handle during installation. Its round shape and bolt-on design simplify the upgrade process, and it produces a signature Borla tone that appeals to enthusiasts of older Mustangs. However, the weight might be a concern for some, and this system’s design limits compatibility to specific years and models. While it doesn’t match the latest performance tech, it still offers a meaningful upgrade for vintage Mustang owners seeking improved performance and sound.
Pros:- Durable T-304 stainless steel construction
- Enhanced power and exhaust flow
- Signature Borla sound with easy bolt-on fit

Flowmaster 17213 American Thunder Cat-Back Exhaust Kit for 1987-1993 Ford Mustang LX 5.0 and 1986 Mustang GT
This Flowmaster kit emphasizes a muscular, aggressive exhaust note that enhances the character of older Mustangs. Its mandrel-bent aluminized tubing and stainless steel tailpipes provide durability, while the Super 44 mufflers deliver a potent, deep sound that appeals to muscle car fans. The design simplifies installation, with factory hanger compatibility making it accessible for DIY enthusiasts or professional installers. Compared to the Borla systems, Flowmaster’s sound is more raw and pronounced, ideal for those who want their Mustang to sound as powerful as it performs. The aluminized steel offers good corrosion resistance, but it’s not as long-lasting as full stainless steel. Overall, this kit balances sound, performance, and ease of fitting for classic Mustang owners.
Pros:- Aggressive, muscular exhaust tone
- Easy installation with factory hanger compatibility
- Durable aluminized steel and stainless steel tips
Cons:- Aluminized steel may be less corrosion-resistant long term

This DNA Motoring system stands out for its robust stainless steel construction and aggressive sound, making it a solid choice for V6 Mustang owners seeking a noticeable performance boost. Compared to the DNA MOTORING Stainless Steel Cat Back Exhaust System, this model offers a slightly more refined fit and finish, thanks to TIG-welded CNC flanges, but both deliver similar horsepower gains and sound profiles. Its 4.5-inch diameter ensures improved exhaust flow, translating to increased horsepower and torque, especially suited for those wanting a deep, commanding tone. The main tradeoff is that installation can be challenging without mechanical experience, and the louder sound might be too aggressive for some.

Pros:- Significant horsepower and torque gains for V6 models

This DNA MOTORING system provides a solid balance of increased horsepower—up to 25 HP—and a deep, aggressive exhaust tone, making it a versatile upgrade for V6 Mustang owners. Compared with the DNA Motoring CBE-FM10V6-NRT Muffler, this version includes dual rounded tips and a removable silencer, offering a customizable sound experience. Its T-304 stainless steel with mandrel bends ensures durability and corrosion resistance, while the 2.5-inch inlet/outlet size optimizes exhaust flow. The inclusion of a removable silencer allows users to switch between a quieter or louder sound, appealing to those who want flexibility. However, installation might be more complex for those without mechanical skills, and louder sound levels could be off-putting for daily drivers. This system is well-suited for enthusiasts wanting power and sound customization in a durable package.

Factors to Consider When Choosing Performance Exhaust Systems For Ford Mustang
Choosing the right performance exhaust system for your Ford Mustang involves more than just picking the loudest or most expensive option. It’s important to consider how the system complements your driving style, your budget, and the sound level you desire. Additionally, compatibility with your specific Mustang model and ease of installation are key. Here are some factors to keep in mind to make an informed decision:Performance Gains
Look for systems that advertise measurable horsepower and torque improvements. These gains are often achieved through better airflow and reduced backpressure, but the actual results depend on the system’s design and your engine setup. Keep in mind that some systems may emphasize sound more than pure performance, so consider your primary goal—whether it’s maximum power or a balanced sound and performance combo.
Sound Level and Tone
The exhaust sound can range from mild and throaty to ear-shattering loud. Decide how much noise you’re comfortable with, especially if you plan to use your Mustang daily or in areas with noise restrictions. Some systems are tunable, allowing you to adjust the tone, while others maintain a fixed aggressive or deep sound. Remember that louder systems may also attract more attention and potentially more noise violations.
Material and Durability
Stainless steel is the gold standard for longevity, resisting rust and corrosion better than aluminized steel or other materials. Pay attention to the quality of welds and the type of stainless used—higher-grade stainless offers better durability and aesthetics. A well-made system can last many years, making it a worthwhile investment, especially if you plan to keep your Mustang long-term.
Installation and Compatibility
Some exhaust systems are straightforward bolt-ons suitable for DIY installation, while others might require professional help. Verify compatibility with your specific Mustang year and engine type, as fitment issues can arise otherwise. Consider whether you want a complete cat-back system or just an axle-back upgrade, as this impacts both cost and complexity.
Cost and Value
Price ranges widely, with premium systems offering advanced materials and sound tuning, while budget options focus on basic functionality. Balance your budget against your desired performance and sound outcome. Sometimes spending a little more upfront results in a longer-lasting, better-sounding system that enhances your driving experience significantly.
Frequently Asked Questions
Will upgrading my exhaust system increase my Mustang’s horsepower?
Yes, a well-designed performance exhaust system can improve horsepower and torque by reducing backpressure and improving airflow. However, the actual gains depend on your engine configuration and whether other modifications are present. For maximum benefit, consider pairing the exhaust upgrade with other performance modifications such as a tune or intake system.
How loud can I expect my Mustang to be with a performance exhaust?
The sound level varies considerably based on the system chosen. Some systems, like the SLP LoudMouth, are extremely loud and suited for enthusiasts seeking maximum volume. Others, like Borla’s systems, offer a deep, aggressive tone but remain less intrusive in daily driving. Always check decibel levels if available and consider your noise preferences before choosing a system.
Is it worth paying more for a stainless steel exhaust system?
Investing in stainless steel generally provides better durability and corrosion resistance, which is especially important if you live in a region with harsh weather or road salt. While stainless systems tend to be more expensive initially, their longevity and maintained appearance can make them a cost-effective choice over time. Cheaper materials may rust or degrade faster, potentially leading to additional replacement costs.
Can I install a performance exhaust system myself?
Many bolt-on exhaust systems are designed for DIY installation with basic tools, especially axle-back models. However, some cat-back systems may require more extensive work or professional tools, particularly if modifications to mounts or brackets are needed. Always review the installation instructions carefully and assess your mechanical skills before attempting a full installation.
Will a louder exhaust system cause legal issues or fail emissions tests?
Louder exhausts can sometimes exceed local noise regulations, especially in urban or suburban areas. Additionally, some aftermarket systems may affect emissions compliance depending on your region’s regulations. Check local laws and consider whether a moderate volume system might be more practical for daily driving and legal peace of mind.
Conclusion
For most Mustang owners seeking a balance of performance and sound, the Borla 140585 Cat-Back offers excellent overall value and reliability, making it the best choice for daily drivers who want a strong upgrade. Enthusiasts after maximum volume and aggressive tone might prefer the SLP LoudMouth or premium systems like Borla’s high-end options. Budget-conscious buyers should consider the DNA Motoring CBE-FM05-46GT for a solid upgrade without breaking the bank. If durability and long-term performance are your priorities, investing in a stainless steel system is worthwhile. Ultimately, your decision should align with your driving habits, sound preferences, and budget, ensuring you get the best fit for your Mustang.
