Catalytic Converter Y-Pipe For Nissan Murano 3.5L 2009-2014 EPA Rear high flow

The three-way catalytic converter can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

The working principle of the three-way catalytic converter is: when high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, prompting them to undergo certain oxidation-reduction chemical reactions. , the metacatalytic reactor is similar to a muffler. Its outer surface is made of double-layer stainless steel sheets into a cylindrical shape. Thermal insulation - asbestos fiber mat - is installed in a double-layer sandwich. The interior contains purifiers between mesh partitions. The purifier consists of carrier and catalyst.
