---tab Description--- Description This DPF Delete Race Pipe is designed for 2004.5–2007 Dodge Ram 2500/3500 with the 5.9L diesel engine. It replaces the restrictive factory DPF (Diesel Particulate Filter) system, improving exhaust flow, performance, and fuel efficiency. Available in 4” or 5” turbo-back configurations, this stainless steel system delivers a deeper exhaust tone, reduced EGTs, and better turbo whistle while eliminating costly DPF maintenance. Specification Material T-409 Stainless Steel, it is magnetic. Thickness 2mm Inlet Diameter 4''/5'' Compatible Fully compatible with factory-style V-band connection (04.5+ turbo elbow required for 5") Key Features Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg. It removes the need to service the DPF at regular intervals (cleaning, replacement) A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs Due to less exhaust backpressure, the Dodge Ram Diesel Truck DPF delete increases exhaust flow and therefore increases the performance of your motor! Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles User Experience & Performance Feedback 4” Turbo-Back: Balanced sound, moderate volume increase over stock, excellent for daily drivers and lightly modified builds. 5” Turbo-Back: Deeper tone, better turbo whistle, lower EGTs, ideal for towing, heavy-duty use, or enthusiasts who want a louder, more aggressive sound.

Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) for emissions reasons, however there are a few disadvantages to this device; including constant maintenance and repairs. For owners to upgrade to a 4 inch or 5 inch turbo back exhaust system, bypassing the DPF entirely for off-road performance. Because the DPF clogs up, it increases backpressure. Due to this pressure, the fuel flow is hugely disturbed and slowed down. Therefore, when you remove this filter, the fuel flows much easily and faster, increasing the overall fuel mileage.
