Setup and Installation
Proper installation is crucial for the performance and longevity of your CAT BACK exhaust system. It is recommended that installation be performed by a qualified technician.
Required Tools and Materials:
- Vehicle lift or jack stands
- Wrench set (metric and/or standard, as required by vehicle)
- Socket set
- Torque wrench
- Penetrating oil
- Safety glasses and gloves
- Exhaust hanger removal tool (optional, but recommended)
Pre-Installation Steps:
- Ensure the vehicle is cool to the touch before beginning work.
- Safely lift and secure the vehicle using a lift or jack stands.
- Locate the existing exhaust system components that will be replaced.
- Apply penetrating oil to all exhaust hangers and fasteners to aid in removal.
Installation Procedure:
- Carefully remove the existing exhaust system components, starting from the rear of the vehicle and working forward. Support the system to prevent it from falling.
- Clean any mating surfaces on the vehicle where the new exhaust system will connect.
- Begin installing the new Mopar CAT BACK system, starting from the front connection point (e.g., catalytic converter or mid-pipe).
- Securely attach all pipes, mufflers, and tips using the provided clamps and hardware. Do not fully tighten fasteners until the entire system is in place and aligned.
- Ensure proper clearance between the exhaust system and all vehicle components (e.g., suspension, driveshaft, fuel lines). Adjust as necessary.
- Once the entire system is aligned and clearances are confirmed, progressively tighten all fasteners to the manufacturer's specified torque settings.
- Double-check all connections for tightness and proper alignment.
- Lower the vehicle safely.
Operating Considerations
After installation, the new exhaust system may produce a different sound profile compared to the stock system. This is normal for performance exhaust systems.
- Initial Break-in: During the first few hundred miles, the exhaust system may emit a slight burning smell as manufacturing oils and coatings burn off. This is normal and will dissipate.
- Sound Characteristics: The CAT BACK system is designed to enhance the vehicle's exhaust note. Sound levels may vary based on engine RPM, load, and driving conditions.
- Temperature: Exhaust components operate at high temperatures. Avoid touching the system immediately after operation.
Maintenance
Regular inspection and minor maintenance will help ensure the longevity and optimal performance of your Mopar CAT BACK exhaust system.
- Periodic Inspection: Every 6-12 months, or during routine vehicle service, inspect the entire exhaust system for signs of damage, corrosion, loose connections, or worn hangers.
- Check for Leaks: Listen for any hissing or blowing sounds that might indicate an exhaust leak. Leaks can also be identified by black soot marks around joints.
- Hanger Condition: Ensure all rubber hangers are intact and not cracked or deteriorated. Replace any worn hangers to prevent rattles or excessive movement.
- Cleaning: The exterior of the exhaust system, especially polished tips, can be cleaned with mild soap and water. Avoid abrasive cleaners that may scratch the finish.
- Fastener Torque: Periodically check the torque of all clamps and fasteners, especially after the first few hundred miles of operation, as heat cycles can cause them to loosen slightly.
Troubleshooting
This section addresses common issues you might encounter with your exhaust system.
| Problem | Possible Cause | Solution |
|---|---|---|
| Rattling or Vibrations | Loose clamps/fasteners; exhaust system contacting vehicle chassis; worn or damaged hangers. | Check and tighten all fasteners; adjust exhaust system position to ensure proper clearance; inspect and replace worn hangers. |
| Excessive Noise / Hissing Sound | Exhaust leak at a joint or weld; damaged muffler or resonator. | Inspect all connections for leaks and tighten or seal as necessary; inspect muffler/resonator for damage and replace if needed. |
| Exhaust Tip Misalignment | Improper initial alignment; loose hangers or clamps. | Loosen clamps, adjust tip position, and re-tighten; check and adjust hangers. |
If you encounter issues not listed here or are unable to resolve a problem, please consult a qualified automotive technician.
