Review YOSHIMURA Exhaust fits AT2

The **Yoshimura 960-2551 ZX4RR AT2 Exhaust** is a meticulously engineered aftermarket exhaust system designed exclusively for Honda s legendary **NSX Type R (ZX4RR)** and its high-performance **AT2** variant, delivering an unparalleled blend of raw power, precision aerodynamics, and show-stopping aesthetics. Crafted from **high-grade 304 stainless steel** with a **polished finish**, this exhaust system is built to withstand the extreme demands of track use while maintaining a sleek, factory-inspired appearance that turns heads on the street. The **960-2551** model features a **dual-outlet configuration** with **4.5-inch diameter exhaust tips**, optimized for both performance and visual impact, ensuring a deep, resonant exhaust note that grows louder and more aggressive as RPMs climb. The system incorporates **Yoshimura s proprietary "Flow-Through" design**, which minimizes backpressure while maximizing airflow through the catalytic converters and mufflers, allowing the AT2 s twin-turbocharged V6 to breathe more freely and extract every ounce of power from its forced induction setup. The **AT2-specific tuning** ensures compatibility with the NSX s advanced turbocharging system, including the **variable geometry turbochargers (VGT)** and **intercoolers**, resulting in improved throttle response and a more linear power delivery curve. Beyond performance, the exhaust system is engineered with **aerodynamic precision**, featuring **smooth, contoured piping** that integrates seamlessly with the NSX s aggressive bodywork, reducing drag and enhancing downforce critical for track performance. The **polished stainless steel finish** is not only visually striking but also highly durable, resisting corrosion and maintaining its shine even under the harshest conditions, whether on a racetrack or during daily driving. For enthusiasts seeking a balance between **street-legal compliance** and **track-ready performance**, the Yoshimura 960-2551 is a standout choice, offering a **factory-inspired yet bold upgrade** that elevates both the sound and the presence of the ZX4RR AT2. Whether you re chasing lap times at the track or making a statement on the road, this exhaust system delivers a **harmonious fusion of function and form**, proving that Yoshimura s attention to detail remains unmatched in the world of high-performance automotive aftermarket parts.

### Pros and Cons of Buying a Yoshimura 960-2551 ZX4RR AT2 Exhaust System

#### **Pros**

1. **Performance Enhancement** The Yoshimura 960-2551 is designed for the Nissan Z (Z33) and is optimized for the AT2 engine variant. It features a larger diameter exhaust system (2.5 inches) that improves exhaust flow, reducing backpressure and allowing the engine to breathe better. This can lead to a noticeable increase in horsepower and torque, particularly in the mid-to-high RPM range.

2. **Sound Quality** Yoshimura exhaust systems are known for producing a deep, aggressive, and well-balanced exhaust note. The 960-2551 is particularly praised for its smooth yet powerful tone, which is more refined than many aftermarket exhausts that prioritize volume over harmony. It strikes a good balance between street-legal sound and track performance.

3. **Durability and Quality** Yoshimura is a reputable manufacturer that uses high-quality materials, including stainless steel and heavy-duty construction. The 960-2551 is built to last, with reinforced welds and corrosion-resistant components. This makes it a reliable choice for both daily driving and track use.

4. **Compatibility** This exhaust is specifically designed for the ZX4RR AT2 engine, ensuring a proper fit with minimal modifications required. It includes all necessary mounting hardware and is compatible with the stock catalytic converter (though some owners opt to remove it for better performance).

5. **Aesthetic Appeal** The exhaust features a sleek, aggressive design with a dual exhaust setup that enhances the sporty look of the ZX4RR. The polished or matte finish options (depending on the model) add to the car s visual appeal.

6. **Easy Installation** While some aftermarket exhausts require extensive modifications, the Yoshimura 960-2551 is relatively straightforward to install, especially if you have basic mechanical skills or access to a professional installer. It typically requires removal of the stock exhaust and installation of the new system with minimal additional work.

7. **Support and Reputation** Yoshimura has a strong reputation in the tuning community, with extensive customer support and a proven track record of reliability. Many owners report positive experiences with the system s performance and longevity.

#### **Cons**

1. **Cost** Yoshimura exhaust systems are premium products, and the 960-2551 is no exception. Pricing typically ranges from $1,200 to $1,800, depending on whether you include installation, additional components (like a downpipe or muffler), or optional upgrades (e.g., a cat-back or full system). This can be a significant investment for a single component.

2. **Potential for Excessive Noise (If Not Properly Tuned)** While the sound is generally well-balanced, some owners report that the exhaust can be louder than desired on the street, especially if the engine is not properly tuned to match the exhaust system. Without a tune, the car may run rich, leading to a harsh or unrefined exhaust note. A tune from a reputable tuner (e.g., Apexi, Haltech, or Nissan-specific) is highly recommended to optimize performance and sound.

3. **Weight** The larger diameter pipes and heavier construction of the Yoshimura exhaust add weight to the rear of the car. While the impact on handling is minimal for a car like the ZX4RR, some owners may prefer lighter exhaust systems if weight reduction is a priority.

4. **Installation Complexity** While not overly difficult, installing the Yoshimura exhaust may require some mechanical skill or access to specialized tools. If you re not comfortable with exhaust work, hiring a professional installer is advisable. Additionally, some owners may need to modify or replace other components (e.g., the catalytic converter, hangers, or heat shields) for a perfect fit.

5. **Potential for Catalytic Converter Issues** If you choose to keep the stock catalytic converter, the increased exhaust flow may cause it to overheat or fail prematurely. Some owners opt to remove the cat or install a high-flow alternative, which can void emissions compliance in some regions. This is something to consider if you plan to keep the car street-legal without modifications.

6. **Limited Customization** Unlike some aftermarket exhausts that offer multiple muffler or pipe configurations, the Yoshimura 960-2551 has a fixed design. If you re looking for extreme sound levels or a completely custom setup, you may need to pair it with additional components (e.g., a different muffler or resonator).

7. **Resale Value Impact** While the Yoshimura exhaust is a high-quality upgrade, it may not significantly increase the resale value of your ZX4RR. Buyers often prioritize the car s overall condition, mileage, and originality, so the benefit may be more subjective (enjoyment and performance) than financial.

### **Conclusion**

The Yoshimura 960-2551 is one of the best exhaust systems available for the Nissan ZX4RR AT2, offering a compelling blend of performance, sound quality, and durability. It is particularly well-suited for owners who want a noticeable power increase without sacrificing a refined exhaust tone. The system is a solid choice for both street and track use, provided it is paired with a proper tune and installed correctly.

However, the high cost, potential noise concerns (if not tuned), and the need for careful installation are factors to consider. If you re willing to invest in a premium exhaust system and are prepared for the associated costs and minor trade-offs, the Yoshimura 960-2551 is an excellent upgrade. For those on a tighter budget or seeking a more aggressive sound, alternatives like the Borla or MagnaFlow exhausts may be worth exploring, though they may not offer the same level of performance or sound quality.

---

### **Recommendation**

- You want a high-quality, performance-focused exhaust system that enhances both power and sound.

- You re willing to invest in a premium product and are prepared for the associated costs.

- You plan to tune your car to optimize performance and ensure a balanced exhaust note.

- You prioritize durability and reliability for daily driving or track use.

- You appreciate a well-balanced, aggressive yet refined exhaust tone.

- You re on a tight budget and can t justify the cost of a Yoshimura system.

- You prefer a louder, more aggressive exhaust sound and are willing to sacrifice some refinement.

- You re not comfortable with installation or tuning and prefer a simpler, more DIY-friendly exhaust system.

- You re concerned about emissions compliance and want to avoid modifications to the catalytic converter.

**Final Verdict:** The Yoshimura 960-2551 is a top-tier exhaust system for the ZX4RR AT2 and is highly recommended for serious Z owners who want to maximize performance and sound quality. Just be prepared for the investment and ensure it s paired with a proper tune for the best results.
