The Nissan 370Z is a popular sports car known for its performance and tuning potential. One of the most common modifications enthusiasts consider is upgrading the exhaust headers. In this article, we will compare two aftermarket header options: the $1,500 Stillen headers and the $2,000 Motordyne headers. We will analyze their design, power gains, installation process, and overall value to help you make an informed decision for your Nissan 370Z.
Overview of Aftermarket Headers
Aftermarket headers are designed to improve exhaust flow from the engine, which can lead to increased horsepower and torque. By replacing the factory headers, enthusiasts aim to enhance the performance of their Nissan 370Z. Both Stillen and Motordyne offer high-quality headers, but they have distinct features that may appeal to different drivers.
Stillen Headers
The Stillen headers are known for their quality construction and performance gains. Priced at $1,500, they are a popular choice among Nissan 370Z owners looking for a balance between cost and performance.
Design and Features
The Stillen headers feature a 304 stainless steel construction, which offers durability and resistance to corrosion. They are designed with equal-length primary tubes to ensure optimal exhaust flow. The headers also come with high-flow catalytic converters, which help to reduce back pressure while maintaining emissions compliance.
Power Gains
Owners who have installed Stillen headers report power gains of approximately 15-20 horsepower at the wheels. This increase can be attributed to the improved exhaust flow and the efficient design of the headers.
Installation Process
The installation of Stillen headers typically requires about 4-6 hours, depending on the experience of the installer. While some DIY enthusiasts may attempt the installation themselves, professional installation is recommended to ensure proper fitment and performance.
Motordyne Headers
Motordyne headers, priced at $2,000, are known for their unique design and performance-focused features. They are a premium option for those looking to maximize their Nissan 370Z’s potential.
Design and Features
The Motordyne headers are also constructed from 304 stainless steel and feature a unique design that includes a tri-y configuration. This design aims to optimize exhaust scavenging and enhance power delivery across a broader RPM range. Additionally, the headers come with high-flow catalytic converters, designed to improve exhaust flow while meeting emissions standards.
Power Gains
Users have reported power gains of approximately 20-25 horsepower at the wheels after installing Motordyne headers. The tri-y design is particularly effective in improving mid-range torque, making it a great option for street driving.
Installation Process
The installation of Motordyne headers can take slightly longer, around 5-7 hours. Like the Stillen headers, professional installation is recommended to ensure optimal performance and fitment.
Comparative Analysis
When comparing the Stillen and Motordyne headers, several factors come into play, including price, power gains, design, and ease of installation. Below is a summary of the key differences:
- Price: Stillen ($1,500) vs. Motordyne ($2,000)
- Power Gains: Stillen (15-20 hp) vs. Motordyne (20-25 hp)
- Design: Stillen (equal-length) vs. Motordyne (tri-y)
- Installation Time: Stillen (4-6 hours) vs. Motordyne (5-7 hours)
Conclusion
Both the Stillen and Motordyne headers offer significant performance improvements for the Nissan 370Z. The choice between the two largely depends on your budget and performance goals. If you are looking for a more cost-effective option with solid gains, the Stillen headers are a great choice. However, if you are willing to invest more for potentially higher power gains and a unique design, the Motordyne headers may be the better option.
Ultimately, the best choice will depend on your specific needs as a driver and how you plan to use your Nissan 370Z. Consider your goals, budget, and preferences to make the best decision for your vehicle.
