The Nissan 300ZX, particularly the Z32 model, is a beloved sports car known for its sleek design and impressive performance. However, like any vehicle, there’s always room for improvement. One of the most effective upgrades for enhancing power and performance is the exhaust system. In this article, I will share my experience with a $2,500 exhaust system upgrade and the real-world results it delivered.
Why Upgrade the Exhaust System?
The stock exhaust system on the Z32 is designed to meet emissions standards while providing adequate performance. However, it often restricts airflow, which can limit the engine’s potential. Upgrading to a high-performance exhaust system can:
- Improve exhaust flow
- Enhance engine sound
- Increase horsepower and torque
- Reduce overall weight
The Exhaust System I Chose
After extensive research, I decided to invest in a $2,500 aftermarket exhaust system specifically designed for the Z32 300ZX. This system included:
- Stainless steel construction for durability
- High-flow catalytic converters
- Mandrel-bent piping for smooth airflow
- Performance mufflers for an aggressive sound
Installation Process
Installing the new exhaust system was a straightforward process, but it required some mechanical knowledge. Here’s a brief overview of the steps involved:
- Lift the car securely using jack stands.
- Remove the stock exhaust system, starting from the headers to the tailpipes.
- Install the new exhaust components, ensuring all connections are tight.
- Lower the car and check for leaks before taking it for a test drive.
Real-World Results
After the installation, I was eager to see how the new exhaust system impacted my Z32’s performance. Here are the results I observed:
- Increased horsepower: The dyno showed an increase of approximately 30 horsepower.
- Improved torque: Torque increased by about 25 lb-ft, making acceleration feel more responsive.
- Enhanced sound: The exhaust note transformed from a quiet hum to a deep, aggressive growl that turned heads.
- Weight reduction: The new system was significantly lighter than the stock setup, contributing to better handling.
Driving Experience
The driving experience after the exhaust upgrade was nothing short of exhilarating. The car felt more alive, and the added power was noticeable during acceleration. Here are some aspects of the driving experience that stood out:
- Smoother power delivery: The engine felt more responsive, especially in the mid-range RPMs.
- Better throttle response: The car reacted more quickly to accelerator input, enhancing the overall driving experience.
- Exciting engine sound: The aggressive exhaust note added a new layer of enjoyment to driving the Z32.
Considerations Before Upgrading
While the upgrade delivered impressive results, there are a few considerations to keep in mind:
- Cost: A $2,500 exhaust system is a significant investment, and it may not fit every budget.
- Emissions compliance: Ensure the system meets local emissions regulations to avoid legal issues.
- Potential drone: Some aftermarket systems can produce drone at certain RPMs, which might not be appealing to all drivers.
Conclusion
Upgrading the exhaust system on my Z32 300ZX was a transformative experience that significantly boosted its power and performance. The $2,500 investment delivered real-world results that exceeded my expectations. If you’re considering an upgrade, weigh the benefits against your budget and preferences, and enjoy the thrill of enhanced driving.
