The ND Miata has captured the hearts of enthusiasts around the world with its lightweight design and agile handling. However, for many, the quest for improved performance leads to aftermarket modifications. One popular upgrade is the exhaust system, and today we will dive into the cost versus performance of the $2,000 RoadsterSport Exhaust.
Overview of the ND Miata
The fourth-generation Miata, known as the ND, was introduced in 2015. It features a 2.0-liter four-cylinder engine that produces 181 horsepower and 151 lb-ft of torque. With its rear-wheel-drive layout and near-perfect weight distribution, the ND Miata is a favorite among driving purists.
Understanding Exhaust Systems
An exhaust system plays a crucial role in a vehicle’s performance. It helps to expel gases from the engine, reduces back pressure, and can enhance the sound of the engine. Upgrading to a performance exhaust can provide several benefits:
- Improved horsepower and torque
- Enhanced engine sound
- Weight reduction
- Better fuel efficiency
The RoadsterSport Exhaust: Features and Specifications
The RoadsterSport Exhaust is designed specifically for the ND Miata, promising to deliver a perfect blend of performance and sound. Here are some key features:
- High-quality stainless steel construction
- Mandrel-bent piping for improved flow
- Lightweight design
- Aggressive exhaust note without being overly loud
Installation Process
Installing the RoadsterSport Exhaust is designed to be straightforward, typically taking about 1-2 hours. Here’s a brief overview of the installation steps:
- Gather necessary tools: socket set, jack stands, and safety glasses.
- Lift the vehicle and secure it on jack stands.
- Remove the stock exhaust system by unbolting the hangers and clamps.
- Install the RoadsterSport Exhaust, ensuring all connections are secure.
- Start the engine and check for leaks.
Performance Testing
To evaluate the performance of the RoadsterSport Exhaust, we conducted a series of tests comparing it to the stock exhaust. The tests focused on horsepower gains, torque improvements, and sound levels.
Dyno Testing Results
Using a dynamometer, we measured the power output of the ND Miata with both exhaust systems. The results were as follows:
- Stock Exhaust: 181 hp and 151 lb-ft of torque
- RoadsterSport Exhaust: 195 hp and 158 lb-ft of torque
The RoadsterSport Exhaust showed a notable increase in both horsepower and torque, highlighting its performance benefits.
Sound Level Comparison
Sound is a significant aspect of any exhaust upgrade. We measured the sound levels using a decibel meter:
- Idle (Stock): 70 dB
- Idle (RoadsterSport): 75 dB
- Full throttle (Stock): 85 dB
- Full throttle (RoadsterSport): 90 dB
The RoadsterSport Exhaust provided a deeper, more aggressive tone while still remaining comfortable for daily driving.
Cost Analysis
At $2,000, the RoadsterSport Exhaust is a significant investment. However, when evaluating cost versus performance, it’s essential to consider:
- Performance gains: The increase in horsepower and torque can translate to better acceleration and driving enjoyment.
- Material quality: The stainless steel construction ensures durability and longevity.
- Resale value: Performance upgrades can enhance the resale value of the vehicle.
Conclusion
Overall, the RoadsterSport Exhaust offers a compelling blend of performance and sound for ND Miata owners. With noticeable gains in horsepower and torque, alongside an aggressive yet refined exhaust note, it stands out as a worthwhile investment for enthusiasts looking to enhance their driving experience.
When considering upgrades, it’s essential to weigh the costs against the benefits. The RoadsterSport Exhaust delivers on its promise, making it a top contender in the aftermarket exhaust market for the ND Miata.
