It is made from 3-inch stainless steel tubing with smooth mandrel-bent curves, two ports for O2 sensors and an additional port for a third sensor.<\/p>\n<p>The turbocharger outlet measures almost 4\u2033 before narrowing to 3\u2033. This design allows exhaust gases to flow smoothly from the turbocharger into the test pipe.
