Why delete your 6.7L Cummins DPF?

By removing the restrictive 6.7 Cummins DPF delete pipe components, you unlock the full potential of your commercial rig:

• Significant MPG Increase: Improve from a clogged 13-14 MPG to an efficient 18-19 MPG combined.
• Zero Maintenance: Eliminates the need for expensive DPF cleanings and DEF fluid refills.
  
• Engine Longevity: Lower exhaust backpressure results in reduced engine strain and cooler operating temperatures.
• Power Gains: When paired with an ECU remap, expect massive torque improvements for heavy hauling.

Installation

DIY-Friendly Install: The install takes about 1 hour with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers, and hardware are included. You may have to re-use some factory hardware.

Mandatory Tuner: This is a race-only exhaust. A DPF-delete capable tuner (e.g., EZ Lynk, Mini Maxx) is required to prevent Diagnostic Trouble Codes (DTCs) and Check Engine Lights.

⚠️⚠️⚠️FOR OFF-ROAD & COMPETITION USE ONLY. CHECK LOCAL EMISSIONS LAWS BEFORE PURCHASE.

Q1: Why does my Ram Cab & Chassis need a specific kit?

A1: Cab & Chassis trucks (3500/4500/5500) are built differently. Their frames and gas tanks are not the same as standard pickups. This 6.7 Cummins DPF delete kit is specially shaped to fit around the heavy-duty parts of your commercial truck.

Q2: Will this kit fit a normal Dodge Ram 2500/3500 pickup?

A2: No. This kit is only for Cab & Chassis trucks. If your truck came with a flatbed or a utility box, this is the right one. Normal pickups need a different exhaust pipe.

Q3: Do I need a tuner for this DPF delete?

A3: Yes. You must use a delete-capable tuner (like EZ Lynk or Mini Maxx). Without it, your truck will go into "Limp Mode" and show error codes on the dash.

Q4: Will it save me money on fuel (MPG)?

A4: Yes! Most owners see 3 to 5 more miles per gallon. By removing the DPF, your truck breathes better. This saves you a lot of fuel when hauling heavy loads.

Q5: How does this help 4500 and 5500 work trucks?

A5: Work trucks often sit idling for a long time. This makes the DPF clog up fast. This 6.7 Cummins DPF delete kit stops those clogs. It saves you from expensive repairs and keeps your truck on the road.

Q6: Should I choose a 4-inch or 5-inch pipe?

A6: The 4-inch pipe is the most popular for work trucks. It works great and fits perfectly. The 5-inch pipe is louder and is best if you want a deep "diesel sound" or have a high-power engine.

Q7: Will this fix my DEF sensor error lights?

A7: Yes! This kit and a tuner will bypass the SCR and DEF systems. It stops the "Speed Limited to 5 MPH" warning caused by broken sensors.

Q8: Which is better: Aluminized or Stainless Steel?

A8: Aluminized Steel is cheaper and works well in dry areas. But if you drive where there is a lot of rain or road salt, choose T409 Stainless Steel. It lasts much longer without rusting.

Q9: How long does it take to install?

A9: It usually takes 1 to 2 hours. You only need basic hand tools. Since Cab & Chassis trucks have different lengths, you might need to cut a small part of the pipe to fit perfectly.

Q10: Can I use this on the street?

A10: No. This kit is for off-road or race use only. It is not legal to use on public roads in many places. Please check your local laws before you buy.
