- Reconnect any sensors or brackets that were removed earlier.
- Using the original bolts, secure the downpipe to the turbo and exhaust system. Hand-tighten them first.
- Using a torque wrench, tighten the bolts to the manufacturer’s specifications. Refer to your service manual for the correct torque values.
