- Insert the header bolts and hand-tighten them to secure the headers in place.
- Using a torque wrench, tighten the bolts to the manufacturer’s specified torque settings.
Reconnecting the Exhaust System
After securing the headers, reconnect the exhaust system:
- Align the exhaust pipe with the new headers.
- Secure the connection using the appropriate clamps or bolts.
- Check for any leaks or misalignments and adjust as necessary.
