🔧 Fitment Details

✔ For Miata NB Owners: Remove the pre-cut rectangle to accommodate OEM tow hooks.
✔ For Miata NA Owners: Detaching one or both OEM tow hooks is recommended for the best fit.

⚠️ Important Notice – Model Compatibility

• The key difference between 1990-1991 and 1992-2005 Miata models is the rear subframe attachment method.
• Later models (1992-2005) have a rear brace that the diffuser connects to.
• If your 1990-1991 Miata has a newer subframe, you can purchase the kit designed for newer models.

📌 Installation instructions include a diagram showing the rear subframe brace.

🔥 Exhaust Compatibility

💨 Fits most OEM-style and aftermarket exhausts that follow the stock routing.
