Installation Notes and Tips

Confirm the front-left position, inlet style, and outlet connection before ordering. This converter is supplied split and must be welded or clamped together during installation, and the left and right assembly should be ordered as required for the vehicle. Because gaskets are not included, verify all sealing components and sensor connections before final assembly. For California and New York emissions compliance, review the fitment notes carefully before installation.
