{"product_id":"header-w-converter-pipe","title":"Header w\/ Converter Pipe","description":"This 4-to-1 header system replaces all factory components from the cylinder head down to the exhaust B pipe flange, designed to improve exhaust gas velocity and flow. It features equal-length primaries and a high-flow catalytic converter for noticeable performance gains.\n\nThis kit includes the upper header, a lower B pipe with a catalytic converter, an O2 sensor extension harness (to accommodate the moved downstream sensor), a header gasket, a clamp for securing the B pipe to the header outlet, a zip tie for the harness, and bolts for the exhaust connection.\n\nThe MPx Header is reported to produce up to 11 HP and 12 ft-lbs of torque at the wheels, with gains experienced across the powerband without any loss in power or torque. Modern Performance states that check engine lights should not occur with this header; they offer support for troubleshooting if a CEL is triggered. This header is available in two finishes: Raw Steel, suitable for custom coating or wrapping, and Ceramic Coated, which offers improved aesthetics, thermal insulation, and an internal thermal barrier. The ceramic coating should not be wrapped.\n\nWhile the upper section of this header fits all 2.4L engines, the lower catalytic converter section is specific to the Dodge Dart. It will not work on other vehicles like the Compass, Renegade, 200, or Promaster without modification by a local muffler shop or mechanic. If you wish to reduce the exhaust sound or tone, mufflers can be installed on the B pipe or near the exhaust tips, or the MPx Dual Exit exhaust system can be used.","brand":"MPx","offers":[{"title":"Default Title","offer_id":52664230117688,"sku":"MPx-DART-HEADER","price":649.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687548013.jpg?v=1784335557","url":"https:\/\/store.motormia.co\/products\/header-w-converter-pipe","provider":"MOTORMIA","version":"1.0","type":"link"}
