Installation Notes and Tips

Verify the vehicle’s emissions label before ordering, since this converter is listed for California Emissions applications and is not for sale or use in CA, CO, ME, or NY for vehicles with California Emissions. Confirm rear-position undercar fitment and compare the welded 2-bolt inlet and outlet connections to the original exhaust configuration before installation. Because there are no O2 sensor ports, make sure the vehicle’s original layout matches this design.
