How to Install a 6.7 Powerstroke Race Pipe (2011–2022)

This guide details how to install a 6.7 Powerstroke race pipe on a 2011–2022 Ford 6.7L Powerstroke truck. The Race Pipe is primarily used to replace the original DPF section, reducing exhaust back pressure and improving exhaust flow, suitable for off-road, track, or closed-course vehicles.

Legal Notice : This Vigor Diesel 6.7 Powerstroke Race Pipe is only for off-road racing vehicles and is intended for off-road and closed-course racing vehicles only. It is not designed for use on emission-controlled vehicles operated on public roads. By installing this product, you acknowledge and assume all related legal responsibilities and risks.

Required Tools and Checklist

Required Tools

• Socket wrench and ratchet
• Lift or jack + support frame
• WD-40 or other rust inhibitor lubricant
• Safety goggles and protective gloves

Included in Vigor Diesel Race Pipe Kit

• Race Pipe (straight-through exhaust section)
• Mounting flange and connectors
• Pipe clamps (if included in kit)

Some configurations may include a 6.7 Powerstroke race pipe with muffler , depending on the selected race exhaust option.

Precautions & Installation Tips

Before installation, please take the following precautions to ensure a safe and successful installation:

• ECU tuning must be completed before removing the DPF or other emission-related components.
  
• Disconnect the vehicle battery's negative terminal before starting any work. After the engine is off, allow the exhaust system to cool completely for at least 30 minutes to prevent burns.
  
• Exhaust flange bolts and fasteners are prone to corrosion. Before disassembly, apply WD-40 or other penetrating lubricant to all bolts and exhaust hangers and soak them for at least 10 minutes.
• The original DPF assembly is very heavy. Always use a jack or gearbox bracket to support the DPF section before loosening any mounting bolts or flanges.
• Always wear protective gloves and goggles during installation.

Step-by-Step Installation Guide

Step 1: Preparation Before Installation

Park the vehicle on a level surface, engage the handbrake, and disconnect the negative terminal of the battery. After confirming the exhaust system has completely cooled (at least 30 minutes), apply an anti-rust lubricant to all exhaust flange bolts and exhaust hanger locations, and wait at least 10 minutes.

Then, disconnect all sensor connectors and wiring harness clips from the exhaust aftertreatment system, including DOC/DPF/DEF/SCR related sensors.

Step 2: Support and Remove the Front and Rear Flanges of the DPF

At the connection between the exhaust straight pipe and the DPF, use a jack to support the weight of the DPF section.

Remove the flange bolts at this location one by one, and then remove the connecting bolts between the DPF and the front exhaust section. During this step, ensure that the DPF is always supported to prevent sudden sagging.

Step 3: Remove the Exhaust Hangers and DPF

Remove the front and rear mounting brackets of the exhaust hangers. Then pull the DPF towards the rear of the vehicle and remove it. After removing the DPF, reinstall the original exhaust hangers that were just removed back into their corresponding positions on the vehicle for subsequent use on the Race Pipe.

Step 4: Install the Exhaust Hanger and Front and Rear Connecting Sections

First, tighten the screws on the exhaust hanger fixing bracket to ensure the bracket is installed flat and securely. Then, install the straight pipe hanger from the kit to the designated position, adjusting the angle of the hanger to match the installation trajectory of the race pipe, reserving a suitable position for subsequent pipe installation.

Step 5: Install the Race Pipe

Align the Vigor Diesel Race Pipe with the front exhaust section and install the front flange bolts. Then use pipe clamps to connect and secure the front and rear sections of the Race Pipe, ensuring all connections are centered and free from torque.

Step 6: Final Inspection and Tightening

Starting from the front of the vehicle, tighten all flange bolts and clamp bolts evenly to the specified torque, following a diagonal sequence. Ensure sufficient clearance between the exhaust pipe and all underbody components (such as the drive shaft, fuel tank, and body beams) to prevent collision noises during driving. Finally, double-check that all connections are secure.

Special Steps

1. 2017 6.7 Powerstroke Model Adaptation Adjustment

On some 2017 6.7 Powerstroke trucks, minor alignment differences may be observed during installation. If needed, slight adjustment of the flange position can help achieve a proper seal before final tightening.

2. 6.7 Powerstroke Race Pipe with Muffler Installation

If installing the race pipe version with a muffler, ensure the muffler is installed in the correct direction (the "IN" mark on the muffler should face the engine side) when connecting the front and rear sections. Also, allow a 3-5mm vibration gap to prevent interference between the muffler and the frame during vehicle operation, which could cause noises.

Post-Installation: Testing and System Verification

After completing the racing exhaust system installation:

• Reconnect the battery negative terminal and start the engine.
• Let the engine idle for 5-10 minutes.
  
• Carefully inspect all exhaust connections for: hissing sounds, exhaust leaks, black carbon buildup around flanges or clamps.
• Monitor the dashboard to ensure no warning lights are illuminated.
• Confirm the pre-installed ECU tuning is functioning correctly, the engine runs smoothly, and there are no power limits or fault codes.

If any unusual noises, leaks, or warning lights are detected, immediately shut off the engine and recheck all connections, or consult a qualified technician.
