Catalytic Convertor and Exhaust Components

NOTES:
- After performing work on the exhaust system, ensure that the system is not under tension and that there is sufficient clearance to the body. If necessary loosen clamps and mufflers and align exhaust pipes such that there is sufficient clearance to the body over the full length of the exhaust and the supports are uniformly loaded.
- Align exhaust system longitudinally to maintain dimension -a-.
- Replace self-locking nuts.
