1. Borla 140525 Cat-Back System: Best Overall
We evaluated the Borla 140525 and found it stands out due to its aircraft-grade T-304 stainless steel construction, which ensures long-term durability against the elements. Based on manufacturer specifications, the straight-through muffler design minimizes backpressure, effectively improving exhaust flow compared to stock systems.
In our comparison of owner feedback, users consistently praise the aggressive sound profile without the excessive drone often found in cheaper systems. However, buyers seeking a quiet, stock-like ride should skip this model, as the tone is noticeably louder and more pronounced than factory equipment.
- Straight-through design for max flow
- Polished mirror finish for looks
- Million mile warranty included
Pros: Superior corrosion resistance; Aggressive yet refined tone
Cons: Higher initial investment
2. MagnaFlow 11256 Direct Fit Muffler: Premium Runner Up
Our research indicates that the MagnaFlow 11256 offers a compelling balance of performance and sound quality for the Acura TL. The stainless steel construction provides excellent resistance to rust, and the straight-through internal design is engineered to reduce backpressure while maintaining a deep, throaty tone.
Analysis of owner feedback suggests that while the sound is generally praised, some users noted that installation can be difficult without professional welding equipment. If you are looking for a simple bolt-on solution without any fabrication, you might want to consider other options.
- Straight through for less restriction
- Deep tone output
- Fully welded construction
Pros: Easy direct fit installation; Balanced sound quality
Cons: May require professional welding
3. Walker 19131 Quiet-Flow SS: Best OEM Replacement
We compared the Walker 19131 against standard factory parts and found it to be a robust replacement for worn-out stock units. It is designed specifically for those who want to maintain the original quietness of their Acura TL without the drone associated with performance mufflers.
Based on our evaluation of the specs, this unit features a fully stainless steel shell for longevity. However, performance enthusiasts should skip this model, as it does not offer the flow characteristics or sound enhancement required for noticeable horsepower increases.
- Precision bent for exact fit
- OE-like sound levels
- Corrosion resistant aluminized steel
Pros: Factory quiet sound profile; Reliable fit and finish
Cons: Not designed for performance gains
4. Flowmaster 953048 Super 44: Aggressive Sound
The Flowmaster 953048 uses a unique chambered design that we researched extensively, finding it delivers a distinctive, aggressive sound that stands out from straight-through mufflers. It is constructed with heavy gauge steel to withstand tough conditions, though the finish is less resistant to corrosion than premium stainless options.
Owner feedback indicates that while the sound is powerful at idle and acceleration, it produces significant drone at highway cruising speeds. We suggest skipping this product if you frequently drive long distances on the highway and prefer a quieter cabin environment.
- Classic deep tone
- Aggressive interior and exterior sound
- Space age internal components
Pros: Distinctive muscle car sound; Compact size for easy fitment
Cons: Significant highway drone
5. Dynomax 24253 Super Turbo: Value Performance
In our evaluation of budget-friendly exhaust components, the Dynomax 24253 provides a viable option for TL owners looking for mild performance gains without a high cost. The flow-direction design and fiberglass packing are intended to mellow the sound while maintaining efficient exhaust scavenging.
Based on aggregated reviews, the outer shell is susceptible to surface rust over time, especially in regions with heavy road salt use. If you live in a coastal or snowy area and demand maximum corrosion resistance, you may need to look at higher-tier stainless steel models.
- Flow direction design
- Reduces backpressure
- Corrosion resistant coating
Pros: Budget friendly performance option; Improved exhaust flow over stock
Cons: Build quality is average
6. Thrush 17650 Glasspack: Budget Choice
We researched the Thrush 17650 as an entry-level modification for the Acura TL. It features a louvered core design that creates a very loud and aggressive exhaust note, appealing to those who want their vehicle to be heard. The heavy gauge steel construction is robust, but the black paint finish is purely cosmetic.
Our comparison shows that the sound quality can be raspy and lacks the refinement of more expensive brands. Furthermore, the louvered design can create more backpressure than perforated core mufflers. Those looking for a refined performance tone should skip this glasspack.
- Aggressive sound
- Heavy gauge steel shell
- High temperature paint
Pros: Very low cost; Loud and classic tone
Cons: Raspy sound quality
7. Cherry Bomb 87522 Glasspack: Retro Sound
The Cherry Bomb 87522 is a classic glasspack muffler that we evaluated for its distinctively loud sound signature. It utilizes a straight-through design that reduces backpressure effectively, making it a choice for those prioritizing raw sound volume over performance tuning.
Based on our review of owner feedback, this muffler is extremely loud and may violate local noise ordinances in many residential areas. We do not recommend this product for daily drivers who need to maintain a low profile or comply with strict noise regulations.
- Classic glasspack design
- Straight through flow
- Compact size
Pros: Iconic brand recognition; Maximum sound output
Cons: Often too loud for street use
Frequently Asked Questions
Does a new exhaust system add horsepower to the Acura TL?
Yes, replacing the restrictive stock exhaust with a performance system can improve horsepower and torque by reducing backpressure and allowing the engine to breathe more efficiently.
Will an aftermarket muffler make my car louder?
Most aftermarket mufflers will increase the sound level of your vehicle. The amount of noise varies by design, with glasspacks being the loudest and straight-through mufflers offering a deep but manageable tone.
What material is best for exhaust longevity?
Stainless steel, particularly T-304 grade, offers the best resistance to rust and corrosion, making it ideal for longevity. Aluminized steel is a cost-effective alternative but may corrode faster in harsh climates.
Do I need professional installation for an exhaust system?
While some direct-fit mufflers can be installed by experienced DIYers, cat-back systems often require lifting the vehicle and cutting or welding. We recommend professional installation to ensure proper fitment and safety.
What is exhaust drone and how can I avoid it?
Exhaust drone is a low-frequency resonance that occurs inside the cabin at specific RPMs. To avoid it, look for mufflers specifically tuned to eliminate drone or choose systems with resonators included in the design.
Is a cat-back or axle-back system better?
A cat-back system replaces more piping and generally offers better performance gains and sound changes compared to an axle-back, which only replaces the muffler section. The choice depends on your performance goals.
Will aftermarket exhaust void my warranty?
The Magnuson-Moss Warranty Act states that a dealer cannot void your warranty simply because you installed aftermarket parts. However, if the exhaust causes damage to the vehicle, that specific damage might not be covered.
How do I maintain my new exhaust?
Regular cleaning with mild soap and water helps remove road salts and grime. Inspecting the system periodically for rust, loose clamps, or leaks is also recommended to ensure optimal performance.

Based on our research and comparison of specs and owner feedback, the Borla 140525 is the top pick for its exceptional build quality and balanced performance. The MagnaFlow 11256 is the runner up, offering a great blend of sound and value for the Acura TL.
