Review on MagnaFlow 459006 Universal Catalytic Converter by Juan Harrington

Worked well, check English. The light went out immediately after installation. The airflow has also been improved. Direct replacement after replacement delay with cleaning/reset. Most websites recommend replacing the PO420 "below threshold" because the O2 sensor is quite stiff and it's rarely a problem for people to "guess" what needs to be changed. Rough idle could be a vacuum leak, same code could appear Replacing an old autocat, recommended for anyone who hates smog test days.
