{"product_id":"3-5-inch-304-stainless-steel-down-pipe","title":"3.5-Inch 304 Stainless Steel Down Pipe","description":"The PPE 3.5-inch down pipe addresses exhaust restrictions found in the factory system of 2017-2025 GM 2500HD and 3500HD trucks equipped with the 6.6L Duramax L5P engine. By replacing the restrictive, crushed oval-shaped OEM pipe with a smooth, round 304 stainless steel construction, this component facilitates improved exhaust flow, which can contribute to better turbocharger efficiency and response.\n\nThe system features fully machined and TIG-welded flanges that provide a robust, leak-free connection. To manage thermal output, each unit includes a woven titanium heat sleeve that effectively insulates the pipe to reduce engine bay temperatures.\n\nIt features a factory-style V-band connection and retains the original equipment sensor port (M14-1.5) for seamless compatibility with factory sensors. Note that if the 9th injector has been deleted, this down pipe does not include a plug for the injector hole; a separate M20-1.5 plug will be required for proper sealing.","brand":"PPE","offers":[{"title":"Default Title","offer_id":52663322247480,"sku":"117000800","price":188.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527801.jpg?v=1784325936","url":"https:\/\/store.motormia.co\/products\/3-5-inch-304-stainless-steel-down-pipe","provider":"MOTORMIA","version":"1.0","type":"link"}
