Just a friendly heads-up: This catalytic converter is specifically designed without an oxygen sensor bung (no pre-drilled port).
If your vehicle needs an oxygen sensor port to work properly, modification will be required—and this product works with professional mods (e.g., drilling or welding a bung) to add it.
To ensure a good fit, we recommend double-checking if your vehicle requires this port before purchasing. Thank you for your attention!
