Installation Notes and Tips

Verify the vehicle year, make, model, and emissions configuration against the fitment list before ordering. Body fitment must match the exact application shown for each vehicle, including California notes where listed. For best results, inspect related exhaust components, oxygen sensors, and flange condition during replacement so the new converter can be installed on a clean, leak-free exhaust system.
