Installation Steps (General Guidelines):

- Remove Old System: Carefully unbolt and remove the existing axle-back exhaust components. You may need to lubricate rusted bolts.

Operating Considerations
The Gibson Performance Exhaust system is designed to optimize your vehicle's performance and sound. After installation, you may notice a change in exhaust tone, which is characteristic of a performance exhaust system. The system features all-welded construction, baffled, and chambered design for efficient volume and unrestricted flow, meaning there is no packing material to deteriorate over time.
The exhaust exit is designed to be straight out the back of the vehicle.
Maintenance
The Gibson Stainless Steel Axle Back Exhaust System requires minimal maintenance due to its durable construction. Regular inspection is recommended to ensure longevity and optimal performance.
Recommended Maintenance:
- Periodic Inspection: Annually or during routine vehicle maintenance, inspect all hangers, clamps, and connections for tightness and signs of wear or corrosion.
- Cleaning: The polished T304 stainless steel tips can be cleaned with a non-abrasive metal polish to maintain their shine. Avoid harsh chemicals that may damage the finish.
- Damage Check: After driving over rough terrain or if you experience any impact to the underside of your vehicle, inspect the exhaust system for dents, cracks, or dislodged components.
Troubleshooting
If you encounter issues with your Gibson Performance Exhaust system, consider the following common troubleshooting steps:
| Symptom | Possible Cause | Solution |
|---|---|---|

| Exhaust Leak | Improperly tightened clamps; damaged gasket (if applicable); crack in tubing. | Inspect all connections for leaks. Tighten clamps. Replace any damaged gaskets. For cracks, professional repair may be required. |
