1. Borla 140590 Cat-Back Exhaust: Best Overall
In our evaluation of the Borla 140590, we found that the austenitic stainless steel construction provides exceptional resistance to corrosion, backed by a million mile warranty. The system utilizes a straight through muffler design and mandrel bent piping, which manufacturer data indicates reduces backpressure and optimizes exhaust flow. Owner feedback consistently praises the aggressive yet refined tone, distinguishing it from cheaper alternatives.
However, we observed that the premium nature of this system places it at a higher price point, which may not fit every budget. Additionally, some owners report that the interior resonance can be pronounced during highway cruising, making it less suitable for those who prioritize a quiet cabin over performance sound.
- Straight through muffler design for maximum flow
- Includes mandrel bent pipes and chrome tip
- Million mile warranty for stainless steel construction
Pros: Superior build quality with premium materials; Significant horsepower and torque gains based on specs
Cons: Higher investment compared to aluminized systems; Cabin drone can be noticeable at certain RPMs
2. MagnaFlow 15140 Street Series: Premium Choice
We compared the MagnaFlow 15140 to other street series mufflers and noted its acoustic balance is a key strength. The straight through design allows for efficient gas exit, while the packed stainless steel mesh dampens harsh frequencies. Our research indicates that the fully welded body and stainless steel internal components offer excellent protection against the elements.
A limitation we identified is that while the performance gains are solid, the sound remains relatively tame compared to chambered mufflers. Enthusiasts seeking an extremely loud or raspy note might find this option too restrained. It is best suited for drivers wanting a performance upgrade that maintains civility.
- Straight through design for free flowing exhaust
- 5 by 11 inch oval body for deep tone
- Fully welded construction for durability
Pros: Deep, mellow sound profile without excessive drone; High quality stainless steel ensures long life
Cons: Requires professional installation for best results; Not as loud as some aggressive race mufflers
3. Flowmaster 817547 Super 44: Best Aggressive Sound
Based on our research, the Flowmaster 817547 utilizes a distinct chambered design and Delta Flow technology to create its signature sound. The spec sheets highlight the use of larger internal passages to improve flow over older designs. Many owners report satisfaction with the aggressive idle and acceleration notes, making it a popular choice for performance trucks.
However, we found that the chambered design can lead to significant drone inside the cabin during steady state driving. Furthermore, the aluminized steel, while durable, does not offer the same level of corrosion resistance as full stainless steel systems. We recommend this for weekend drivers but suggest caution for those who commute long distances daily.
- Delta Flow technology for scavenging efficiency
- Large case size for superior sound control
- MIG welded for internal strength
Pros: Distinctive, aggressive rumble that truck owners love; Good balance of power and sound control
Cons: Interior drone can be significant at highway speeds; Construction quality is lower than premium stainless brands
4. Dynomax 24253 Super Turbo: Best Value
We evaluated the Dynomax 24253 and determined that its directional louver technology and large case size provide a practical balance of flow and sound absorption. Industry comparisons show it offers a significant improvement over restrictive stock mufflers without the high cost of premium brands. The aluminized steel construction provides acceptable durability for most climates.
A real weakness we noted is that the fiberglass packing material can settle or burn out over extended periods, potentially altering the sound tone. Additionally, while the performance is solid, the build quality does not match that of top tier stainless steel options. This is an excellent choice for budget conscious rebuilds, but not for show truck finishes.
- Large case diameter for maximum flow and sound
- Directional louver technology for turbulence reduction
- Corrosion resistant aluminized steel
Pros: Offers good performance gains at a reasonable price; Reduces backpressure effectively for older trucks
Cons: Fiberglass packing can degrade over time reducing sound dampening; Louder than stock but less refined than premium models
5. Walker 18742 Quiet-Flow SS: Best OEM Replacement
Our analysis of the Walker 18742 highlights its strengths as a direct fit OEM replacement component. The muffler features internal flow directors that maintain exhaust efficiency while keeping noise levels at a minimum. We found the stainless steel construction ensures a long lifespan, addressing common rust issues found in factory parts.
However, this product is not designed for performance enhancement, so truck owners looking for increased horsepower or a sporty sound will likely be disappointed. It is purely functional. We recommend this for fleet vehicles or daily drivers where reliability and quiet operation are the primary concerns.
- 100 percent stainless steel construction for corrosion resistance
- Domestically made in the USA
- Internal flow directors for balanced sound
Pros: Exact fit replacement with no modifications needed; Near stock noise levels for a quiet ride
Cons: Minimal performance gains compared to aftermarket mufflers; Limited visual appeal compared to performance systems
6. Thrush 17650 Glasspack: Budget Pick
In our evaluation of the Thrush 17650, we identified it as a traditional glasspack muffler that delivers a loud, aggressive tone at a low cost. The louvered core design creates the classic raspy sound that many enthusiasts desire. Manufacturer specs indicate it uses high temperature fiberglass to withstand exhaust heat.
We must note that the aluminized steel construction is susceptible to rust, particularly in regions with road salt or high moisture. Additionally, the louvered design can create turbulence that slightly hampers flow compared to straight through perforated cores. This is a suitable option for budget builds or hot rods, but not for long term durability.
- Classic glasspack design for aggressive sound
- High temperature fiberglass packing
- Aluminized steel body
Pros: Very affordable and easy to install; Produces the classic, loud glasspack rumble
Cons: Louvered cores can slightly restrict flow compared to straight pipes; Prone to rust and shorter lifespan than stainless options
7. Cherry Bomb 87522 Glasspack: Honorable Mention
We researched the Cherry Bomb 87522 and found it to be a straightforward glasspack muffler focused on aesthetics and volume. The straight through design allows exhaust gases to exit rapidly, aiding flow in older engines. The red powder coat provides a classic visual appeal that sets it apart from more subdued components.
A significant downside we observed is that the paint finish tends to discolor and burn off quickly once the exhaust heats up. Furthermore, the lack of substantial sound dampening means this muffler is extremely loud, which may not be street legal in all jurisdictions. It is best used for off-road applications or show vehicles where noise is not a concern.
- Red powder coated finish for distinctive look
- Straight through design for maximum flow
- Lightweight construction
Pros: Iconic brand styling and very loud sound output; Inexpensive solution for replacing a rusted muffler
Cons: Powder coating burns off quickly near the tip; Minimal sound dampening leads to potential noise violations
Frequently Asked Questions
Does a new exhaust pipe and muffler improve fuel economy?
Our research indicates that installing a less restrictive exhaust system can improve fuel economy slightly by reducing backpressure and allowing the engine to breathe more efficiently. However, the actual gains are often minimal and depend heavily on driving habits and vehicle condition.
What is the difference between aluminized and stainless steel exhausts?
We compared materials and found that aluminized steel is cost effective and offers decent corrosion resistance through a coating, while stainless steel contains chromium that provides inherent rust resistance throughout the metal. Stainless steel typically lasts significantly longer, especially in harsh climates with road salt.
Will a performance muffler make my truck louder?
In our evaluation, performance mufflers generally produce a louder and deeper tone than stock factory mufflers due to less restrictive internal packing and larger pipe diameters. The exact sound level varies by design, with straight through mufflers being louder than chambered or turbo style mufflers.
How do I measure for a replacement exhaust pipe?
Based on installation guides, you should measure the outside diameter of your existing exhaust pipe where the new component will connect. It is crucial to measure both the inlet and outlet diameters of the muffler or pipe you intend to replace to ensure a proper fit.
Do I need a professional to install an exhaust system?
While we found that many muffler shops offer quick installations, a mechanically inclined individual can install a bolt on system using basic hand tools. However, welding may be required for some custom pipe work, which necessitates professional equipment and safety precautions.
