ISR Performance Circuit Spec Exhaust - Miata NA 1.6

What you get with the ISR Performance Circuit Spec Exhaust for your Miata NA 1.6L is a complete cat-back system designed to improve your car's exhaust note and flow. This kit includes the main exhaust piping, the muffler assembly, and all necessary hangers and hardware for installation. It's built to replace your factory exhaust from the catalytic converter back, giving you a more direct path for exhaust gases to exit the vehicle.

This exhaust is constructed from durable stainless steel, which helps resist corrosion and ensures it holds up over time, even in varying weather conditions. The Circuit Spec design is focused on providing a more aggressive and sporty sound compared to the stock system, without being overly loud or droney for daily driving. The piping diameter and muffler design are optimized to work with the 1.6-liter engine, aiming for improved exhaust gas velocity and a slight bump in responsiveness. Installation is intended to be a direct bolt-on process, meaning no welding or cutting is typically required, making it a straightforward upgrade for many DIYers or a quick job for a mechanic.

When installing this cat-back system, you'll want to ensure you have basic hand tools and possibly some penetrating oil for stubborn factory bolts. It's a popular choice for NA Miata owners looking to add a bit more character to their car's sound and potentially free up a little bit of engine breathing. Make sure to check the manufacturer's instructions for any specific torque recommendations or alignment tips to get the best fit and sound from your new exhaust.
