For 4" DPF Race Pipe 2007.5-2012 Dodge Ram 2500/3500 6.7L Diesel | SPELAB

This 2007.5-2012 Dodge Ram 6.7L Diesel DPF race pipe completely removes the factory DPF unit, creating the most direct exhaust path from the turbo outlet. Engineered for maximum flow efficiency, it significantly reduces exhaust backpressure and lowers EGTs while providing the lightest possible solution for competition vehicles. The straight-through design delivers immediate throttle response and is ideal for track-focused builds where weight savings and unrestricted flow are priorities.

Specification

Benefits

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 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

Installation

Install takes about 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers and hardware are included. You may have to re-use some factory hardware.
Tuner Required: Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.

• This will not fit the Cab & Chassis commercial-style truck. Will not fit trucks with air-ride suspension.

What is the DPF and is it worth doing a DPF Delete?

Most post-2007 diesel vehicles come equipped with a Diesel Particulate Filter (DPF) to meet emissions standards, but this component carries several drawbacks - notably frequent maintenance and repair requirements.

As the DPF becomes clogged, it creates excessive backpressure. This restriction significantly disrupts and slows fuel flow. By removing this filter, fuel can move more freely and rapidly, resulting in improved overall fuel efficiency.

Q1. What’s the difference between 4" and 5" exhaust systems?

• 4" – Better for mild/moderate tunes, retains some backpressure for low-end torque.
• 5" – Best for high-horsepower builds, maximizes flow for reduced EGTs and top-end power.

Q2. Will a magnet stick to this pipe? Is it really stainless steel?

Yes – This pipe uses T-409 stainless steel, which is still magnetic (unlike T-304). It offers excellent corrosion resistance while being more affordable than T-304.

Q3. How thick is the pipe? Will it last?

2mm thick T-409 stainless steel – Durable enough for long-term use without excessive weight.

Q4. Is this street legal?

⚠ Off-Road Use Only – DPF removal is illegal for on-road vehicles in most regions. For competition/racing use only.
