ISR Performance Circuit Spec Exhaust - 06-13 Miata NC

This is the ISR Performance Circuit Spec cat-back exhaust system for the 2006-2013 Mazda Miata NC. This system is designed to replace your factory exhaust from the catalytic converter back, offering a more aggressive sound and improved exhaust flow. It's a popular choice for Miata owners looking to enhance their car's performance and auditory experience, especially for track day or spirited driving applications.

Constructed from durable stainless steel, this exhaust is built to withstand the rigors of daily driving and occasional track use. The Circuit Spec design focuses on maximizing exhaust gas velocity and reducing backpressure, which can lead to a noticeable improvement in throttle response and overall power delivery. The system includes the muffler and all necessary piping to connect to your existing catalytic converter, making installation straightforward for those comfortable working on their vehicle. You'll find the tone to be deeper and more pronounced than stock, without being overly droney at highway speeds, which is a common concern for many enthusiasts.

When installing this cat-back system, ensure you have the proper tools for unbolting the stock exhaust and securing the new one. It's always a good idea to have a helper to assist with maneuvering the exhaust sections. This system is a solid option for Miata NC owners seeking a well-built, performance-oriented exhaust that balances sound and performance.
