The NB Miata is a beloved sports car known for its lightweight design and agile handling. One of the most effective ways to enhance the performance of your NB Miata is by upgrading its intake and exhaust systems. This article will explore the best intake and exhaust combo that can yield a combined power gain of 25 horsepower for less than $1,000.
Understanding the Basics
Before diving into specific products, it’s essential to understand how the intake and exhaust systems work in improving engine performance. The intake system allows more air to enter the engine, while the exhaust system helps expel spent gases more efficiently. Together, they create a more optimal airflow that can significantly boost horsepower.
Top Intake Options for NB Miata
When selecting an intake for your NB Miata, look for options that maximize airflow and improve throttle response. Below are some of the best intake systems available:
- Cold Air Intake System: A cold air intake system is designed to draw cooler air from outside the engine bay, increasing horsepower. Popular brands include AEM and K&N.
- Short Ram Intake: This type of intake is easier to install and provides a noticeable sound improvement. Brands like Injen and Mishimoto offer reliable options.
- Custom Intake Solutions: For enthusiasts looking for a unique setup, custom intakes can be built using high-flow filters and piping.
Best Exhaust Systems for NB Miata
Choosing the right exhaust system is crucial for maximizing power gains. Here are some top exhaust systems for the NB Miata:
- Cat-Back Exhaust Systems: These systems replace the entire exhaust from the catalytic converter back, providing improved flow. Brands like Borla and MagnaFlow are well-regarded.
- Axle-Back Exhaust Systems: A more affordable option, axle-back systems replace the muffler and tailpipe. They are easier to install and can still provide decent power gains.
- Header Upgrades: Replacing the stock headers with performance headers can further improve exhaust flow and increase horsepower.
Combining Intake and Exhaust for Maximum Gains
To achieve the desired 25 horsepower gain, it’s essential to select compatible intake and exhaust systems. The following combinations have proven effective:
- AEM Cold Air Intake + Borla Cat-Back Exhaust: This combo is known for providing excellent power and a sporty sound.
- K&N Short Ram Intake + MagnaFlow Axle-Back Exhaust: A cost-effective solution that still delivers impressive performance.
- Custom Intake + Performance Headers: For those willing to invest more time and effort, a custom setup can maximize power output.
Cost Considerations
When planning your upgrades, it’s crucial to keep track of your budget. Here’s a breakdown of potential costs:
- Intake Systems: Expect to pay between $200 and $400, depending on the brand and type.
- Exhaust Systems: Prices can range from $300 to $600 for quality options.
- Installation Costs: If you’re not comfortable doing the work yourself, factor in an additional $100 to $200 for professional installation.
Installation Tips
Installing an intake and exhaust system can be a rewarding DIY project. Here are some tips to ensure a smooth installation:
- Read Instructions Carefully: Always refer to the manufacturer’s instructions for specific installation steps.
- Gather Necessary Tools: Common tools include wrenches, sockets, and screwdrivers.
- Work in a Well-Ventilated Area: Ensure you have enough space to work and proper ventilation.
Conclusion
Upgrading the intake and exhaust systems of your NB Miata is a fantastic way to enhance its performance without breaking the bank. With careful selection and installation, you can achieve a combined power gain of 25 horsepower for less than $1,000. Whether you choose a cold air intake with a cat-back exhaust or a short ram intake with an axle-back system, the improvements will make your driving experience even more enjoyable.
