The Nissan 370Z is a sports car that has garnered a loyal following due to its performance and tuning potential. One of the key components that car enthusiasts often consider upgrading is the exhaust system. In this article, we will compare the power gains of the Nismo exhaust system versus the OEM setup for the VQ37VHR engine.
Understanding the VQ37VHR Engine
The VQ37VHR is a 3.7-liter V6 engine that powers the Nissan 370Z. Known for its smooth power delivery and high-revving nature, this engine is a favorite among tuners. To maximize its potential, many owners look to aftermarket modifications, particularly exhaust systems.
Nismo Exhaust System Overview
The Nismo exhaust system is designed to enhance the performance and sound of the 370Z. It is a cat-back system that replaces the stock exhaust from the catalytic converter back. This system is engineered to reduce back pressure, allowing for better exhaust flow and improved power output.
Features of the Nismo Exhaust
- High-quality stainless steel construction
- Aggressive exhaust note
- Optimized for performance gains
These features contribute to a noticeable increase in horsepower and torque, making it a popular choice among 370Z owners seeking performance upgrades.
OEM Exhaust System Overview
The OEM exhaust system on the 370Z is designed to meet emissions regulations while providing a balance between performance and comfort. While it is effective for everyday driving, it may not maximize the engine’s potential compared to aftermarket options.
Features of the OEM Exhaust
- Durable construction
- Quieter operation
- Meets all emissions standards
While the OEM exhaust serves its purpose, it often restricts airflow compared to performance-oriented systems like the Nismo exhaust.
Power Gains Comparison
When comparing the power gains from the Nismo exhaust versus the OEM setup, several factors come into play, including engine tuning, vehicle weight, and driving conditions.
Dyno Results
Dyno tests have shown that the Nismo exhaust can provide significant power gains over the OEM system. On average, the Nismo exhaust can yield:
- Increased horsepower: 10-15 whp
- Increased torque: 8-12 lb-ft
These gains can vary based on additional modifications and tuning, but the Nismo exhaust consistently shows improvements in performance metrics.
Sound Comparison
Another important aspect of exhaust systems is the sound they produce. The Nismo exhaust is known for its deep, aggressive tone, which appeals to many sports car enthusiasts.
Sound Characteristics
- More aggressive sound profile
- Enhanced engine growl
- Less drone at cruising speeds
In contrast, the OEM exhaust offers a more subdued sound, which may be preferable for daily driving but lacks the excitement that many drivers seek in a sports car.
Installation and Cost
When considering an upgrade to the Nismo exhaust, installation and cost are important factors. The Nismo exhaust is designed for a straightforward installation, typically taking a few hours with basic tools.
Cost Analysis
- Nismo exhaust system: $1,500 – $2,000
- OEM exhaust replacement: $800 – $1,200
While the Nismo exhaust comes at a higher price point, the performance benefits and enhanced sound may justify the investment for many enthusiasts.
Conclusion
In summary, the comparison between the Nismo exhaust and the OEM setup for the 370Z VQ37VHR engine highlights significant differences in power gains, sound, and overall performance. The Nismo exhaust offers enhanced horsepower and torque, a more aggressive sound profile, and a straightforward installation process, making it an appealing choice for those looking to maximize their vehicle’s potential.
Ultimately, the decision will depend on individual preferences, driving style, and budget. For those who prioritize performance and sound, the Nismo exhaust is a worthy upgrade.
