5-Inch Turbo-Back Exhaust Pipe

The Spelab SPES08122-ES08023SP is a high-performance 5-inch turbo-back exhaust system specifically designed as a DPF and catalytic converter delete pipe for the 2003 Dodge Ram with a 5.9L Cummins diesel engine. Constructed from durable T-409 stainless steel with a 2mm thickness, this exhaust pipe features mandrel-bent tubing engineered for maximum flow efficiency. This design reduces exhaust backpressure, allowing your diesel engine to breathe easier, which can lead to increased turbo response, lower Exhaust Gas Temperatures (EGTs), and improved fuel mileage when paired with an ECU remap. Removing the DPF also eliminates the need for regular DPF servicing and the risk of expensive DPF failure. Installation is estimated to take about 1 hour with basic hand tools, though cutting may be required for certain bed/cab configurations. Clamps, hangers, and hardware are included, though some factory hardware may need to be reused. A DPF-delete capable tuner is required to prevent check engine lights and diagnostic trouble codes, as emission-related sensors are removed. **Important Disclaimer:** This product is for off-road use only and is not legal for street or highway use on emissions-controlled vehicles.
