SPEtuner All-In-One DPF/EGR Delete Kit | 2007.5-2009 Dodge Ram 2500/3500 6.7L Cummins

Maximize the performance, fuel efficiency, and long-term reliability of your 2007.5–2009 RAM 2500/3500 6.7L Cummins with the SPELAB All-In-One Emissions Delete Suite. This comprehensive bundle pairs a high-flow DPF delete race pipe with a complete, heavy-duty EGR delete kit. By eliminating restrictive factory particulate filters and soot-clogged EGR components, this system drastically reduces exhaust backpressure, lowers EGTs, improves turbo spool-up, and prevents endless clogged regeneration cycles. The ultimate plug-and-play solution built for severe off-road and race performance.

Key Features

• Maximum Exhaust Scavenging: Mandrel-bent piping eliminates factory choking points, drastically dropping exhaust backpressure and enhancing turbo response.
• Total EGR Elimination: Completely removes the failure-prone factory EGR cooler and valve to stop soot-laden exhaust gases from choking your intake manifold.
• Lower Exhaust Gas Temperatures (EGTs): Enhances thermal efficiency, keeping operating temperatures safely lower during heavy towing and high-load driving.
• Heavy-Duty Durability: Constructed from premium, corrosion-resistant materials designed to withstand extreme thermal cycles, high boost pressures, and harsh environments.
• Pure Engine Longevity: Keeping abrasive soot and hot exhaust gases out of your intake manifold via the EGR delete ensures your intake valves, pistons, and fuel injectors stay surgically clean for hundreds of thousands of miles.

Specification

• Material: T-409 Stainless Steel, it is magnetic.
• Thickness: 2mm thick for long-lasting durability and heat resistance.
  
• Inlet Diameter: 4"/5"
• Mandrel-Bent Construction: Maximum flow efficiency, helping your diesel breathe easier

Installation

The installation process is relatively simple and can be completed in a driveway or garage using basic hand tools and takes about 1 hour. If you have a car lift, the process will be faster. For some short wheelbase configurations, you may need to make some cuts. All the clips, hooks and hardware required for installation are included, but sometimes it is necessary to reuse some original hardware.

How to Choose Your DPF Delete Kit?

4” vs 5” Straight Pipe Comparison

• 4‑Inch Straight Pipe: Best suited for stock to lightly modified trucks; offers a crisp, aggressive exhaust crackle without overwhelming drone; maintains a quieter interior environment for everyday commuting and light hauling.
  
• 5‑Inch Straight Pipe: Ideal for heavily tuned or competition‑oriented setups; produces a deep, rumbling tone with reduced high‑pitched overtones; maximizes exhaust flow under load, making it the preferred choice for towing, high‑EGT scenarios, and drivers who want a commanding auditory presence

Different Types of DPF Delete

DPF Race Delete

• DPF-only removal for minimal system alteration
• Most economical delete solution available
• Designed for tight budgets or emissions-testing avoidance, not maximum performance gains

Downpipe-Back Delete

• Full replacement from downpipe to tailpipe for unrestricted flow
• Increases torque and throttle response where it matters most on the street
• Perfect for mild street builds that keep the original turbo in place

Turbo Back Delete

• Complete exhaust overhaul from the source
• Maximizes flow efficiency and minimizes backpressure
• Quicker spool and increased peak horsepower
• Ideal for high-performance and heavily modified setups

Muffler vs. No Muffler

With Muffler

• Reduces exhaust noise for improved cabin comfort
• Only 5–10 HP restricted, barely perceptible on the road
• Better chances of passing local sound regulations and inspections

Straight Pipe (No Muffler)

• Bold exhaust note for a commanding auditory presence
• Zero restriction for peak power extraction
• Designed exclusively for track or closed-course use

---tab FAQ---

FAQ

Q1: Will installing this kit cause a Check Engine Light (CEL) if I don't use a tuner?
A1: The 6.7L Cummins ECM monitors exhaust backpressure, DPF soot loads, and EGR flow. Removing these components without recalibrating the ECM will instantly trigger Check Engine Lights, fault codes, and put the engine into limp mode. A delete-capable tuner (e.g., EFI Live, Smarty Touch, or H&S) is required.

Q2: What should I do with the factory EGT and NOx sensors removed during installation?
A2: You will unbolt the factory EGT and NOx sensors from the OEM exhaust and EGR assembly. Once removed, unplug their electrical connectors from the engine harness and store them safely. The delete tuner turns off the sensor monitoring routines, so these sensors are no longer needed.

Q3: Does this kit fit 2007 early-year 5.9L Cummins models?
A3: No. This kit is strictly designed for 2007.5 to 2009 model years equipped with the 6.7L Cummins engine. The 2007 5.9L Cummins features a completely different exhaust system and engine manifold layout that does not use a DPF or EGR cooler system.

Q4: Do I need to make transmission tuning modifications on 68RFE automatic trucks?
A4: While not mandatory for basic operation, recalibrating or tuning the 68RFE automatic transmission is strongly recommended. Deleting the DPF/EGR increases engine torque output and throttle response; adjusting line pressure via transmission tuning helps prevent clutch slippage and extends transmission life.

Q5: What do I do with the factory coolant lines after removing the EGR cooler?
A5: The EGR delete section of the kit includes custom coolant bypass fittings and silicone hoses. You will reroute the coolant loop directly back into the engine block according to the included diagram, ensuring proper engine cooling without coolant leaks or air pockets.

Q6: Will I need extra exhaust hangers or specialized tools for installation?
A6: The exhaust kit is designed to utilize your truck's existing OEM rubber isolator hangers. Basic hand tools, a socket set, penetration oil (PB Blaster for stubborn factory bolts), and a pry bar are sufficient. No specialized pipe benders or welding equipment are needed.

Q7: Will deleting the EGR/DPF affect my engine warmup time in cold weather?
A7: Removing the EGR cooler slightly increases cold-engine warmup time because warm exhaust gas is no longer recirculated through the intake. In extreme winter conditions, allowing the engine a few extra minutes to idle or using a cold-weather grill cover will help achieve normal operating temperatures faster.
