Major-notch significant-effectiveness cats have metallic honeycombs as an alternative to the standard, heavy, and restrictive ceramic honeycombs used on most inventory cats. Metallic catalytic converters also dissipate heat better, heat up more rapidly, are smaller sized, shock resistant, and have additional catalytic capability than their ceramic counterparts. 200-three hundred cell metallic cats are usually plenty of to satisfy pollution restrictions of most US States and European Euro4+ norms.
