| Condition | Some customers may comment on an exhaust leak, noisy exhaust, or noise mid-vehicle. The noise may be described as a rattle or rumble. May be most noticeable on a cold start. |
| Cause | This condition may be caused by an unseated pipe to pipe mid-joint connection as seen below |
Correction
Note: Ensure that the pipe flares remain fully seated to each other while tightening the clamp.
- Remove and discard the exhaust band (Norma) clamp.
- Install and position a new exhaust band (Norma) clamp to the pipe joint.
- Firmly push and maintain the pipes together while tightening the exhaust band (Norma) clamp bolt.
Tighten the clamp bolt to 30 Nm (22 lb. ft.).
Note: After the clamp is installed, it does not need to be perpendicular to the pipe. It is acceptable to have a pipe to pipe or clamp angle.
- Confirm that the clamp edges (both sides and all the way around the clamp) are fully seated on the pipe.
- Run the engine and inspect the clamp joint to ensure there are no leaks and that the condition is corrected.
