{"product_id":"5-turbo-back-exhaust-system-for-5-9l-cummins-diesel","title":"5\" Turbo-Back Exhaust System for 5.9L Cummins Diesel","description":"The SPELAB 5\" Turbo-Back Exhaust System is engineered for high-performance gains on the 2003 Dodge Ram 5.9L Cummins Diesel. This system eliminates DPF and catalytic converter restrictions, leading to lower EGTs, quicker turbo spool, and improved power and torque, especially when paired with an ECU tune. The mandrel-bent T-409 stainless steel construction ensures maximum flow efficiency and long-lasting durability with its 2mm thickness.\n\nInstallation is estimated to take about 1 hour using basic hand tools, though a vehicle lift can speed up the process. Clamps, hangers, and hardware are included, though some factory hardware may need to be reused. Cutting may be required for shorter wheelbase configurations. Crucially, a DPF delete capable tuner is required to prevent check engine lights and diagnostic trouble codes, as emissions-related sensors are removed.\n\nThis exhaust system offers significant benefits beyond performance, including the removal of DPF service requirements (cleaning and replacement) and the elimination of potential DPF failure costs. Owners can expect a noticeable increase in fuel mileage, with potential gains from 13-14 mpg to 18-19 mpg combined after the DPF\/CAT delete, provided the vehicle is properly tuned.\n\n**Important Considerations:**\n*   **Off-Road Use Only:** DPF removal is illegal for on-road vehicles in most regions and is intended for competition or racing use only.\n*   **Tuner Required:** A capable tuner is mandatory to prevent fault codes after removing the DPF and associated sensors.\n*   **Fitment:** Specifically designed for the 2003 Dodge Ram 5.9L Diesel. A 4\" Turbo-Back Exhaust for 2003-2004 Dodge Ram 5.9L Diesel is also available.","brand":"Spelab","offers":[{"title":"Default Title","offer_id":52871962657080,"sku":"SPES08116-ES08023SP","price":569.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/5-turbo-back-exhaust-system-for-5-9l-cummins-diesel","provider":"MOTORMIA","version":"1.0","type":"link"}
