Installation Notes and Tips

Verify vehicle year and exhaust configuration before installation. This converter uses a specific fit for Nissan Altima applications and includes an outlet gasket plus installation hardware for the outlet side. The inlet uses a flanged connection, and the unit does not use sensor ports or air tubes. Confirm flange alignment, gasket seating, and fastener torque during installation to help prevent exhaust leaks.
