The NC Miata is a beloved sports car known for its lightweight design and agile handling. However, many enthusiasts look for ways to enhance its performance and sound without breaking the bank. One popular modification is the installation of an aftermarket header. In this article, we will guide you through the DIY process of installing a header on your NC Miata, focusing on enhancing both power and sound on a budget.

Understanding the Benefits of a Header Upgrade

Before diving into the installation process, it’s essential to understand why upgrading your Miata’s header can be beneficial. Here are some key advantages:

  • Increased Power: A performance header can improve exhaust flow, leading to better engine performance.
  • Enhanced Sound: Aftermarket headers often produce a more aggressive exhaust note, enhancing the driving experience.
  • Weight Savings: Many aftermarket headers are lighter than stock options, contributing to a lower overall vehicle weight.
  • Improved Throttle Response: Better exhaust flow can lead to quicker throttle response, making your Miata feel more lively.

Tools and Materials Needed

Before starting the installation, gather the necessary tools and materials. Here’s what you will need:

  • Aftermarket header designed for NC Miata
  • Socket set and ratchet
  • Torque wrench
  • Jack and jack stands

  • Disconnect the Battery: To avoid any electrical issues, disconnect the negative terminal of the battery.
  • Raise the Vehicle: Use a jack to lift the front of the Miata and secure it with jack stands for safety.
  • Apply Penetrating Oil: Spray penetrating oil on exhaust bolts to help loosen them during removal.

  • Install the New Gasket: Place the new exhaust gasket onto the engine surface.
  • Position the Header: Carefully position the aftermarket header onto the engine, aligning it with the bolt holes.
