Constructed from durable 409 stainless steel and built with a 400-cell honeycomb substrate, the converters focus on reliable flow characteristics while meeting federal EPA standards. They are sold as two pieces and include no oxygen sensor ports or air injection tubes, so install considerations and local regulatory restrictions should be checked before purchase.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the physical specs and material details?\u003c\/h3\u003e\n\u003cp\u003eEach converter has a 2.5\" inside diameter inlet and outlet, and measures approximately 11\" overall. The shell and pipes are made from 409 stainless steel for corrosion resistance and long service life.
