Installation Guide
1. Pre-Installation Checks
Before beginning installation, ensure you have the correct part for your vehicle. It is recommended to consult your vehicle's service manual for specific exhaust system diagrams and procedures.
- Verify the dimensions of the Walker 51115 flex connector against your existing exhaust pipe. The connector features 2.25" Inlet (ID) and 2.25" Outlet (ID).
- Gather all necessary tools, which may include wrenches, pipe cutters, welders (if applicable for weld-on installation), and safety equipment.
- Ensure the vehicle is safely lifted and supported on jack stands or a lift. Allow the exhaust system to cool completely before handling.

2. Removal of Old Component (if applicable)
If replacing an existing flex connector or section of pipe, carefully remove the old component. This may involve cutting the pipe or unbolting flanges.
3. Installation of Walker 51115 Flex Connector
The Walker 51115 flex connector is designed for either weld-on or clamp-on installations, depending on your specific setup and preference.
- Weld-On Installation: Position the flex connector into the exhaust system. Ensure proper alignment and secure the connector by welding it to the existing pipes. Professional welding is recommended.
- Clamp-On Installation: Slide the flex connector onto the exhaust pipes. Use appropriate exhaust clamps (not included) to secure the connection. Tighten clamps evenly to ensure a leak-free seal.
