1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Exhaust System

Tools Required: Socket set, jack and jack stands, exhaust pipe wrench.
Inspect the entire exhaust system for cracks, holes, or loose connections.
Tighten any loose bolts and replace worn gaskets.
If damage is found, remove the affected section of the exhaust using a socket set.
Replace with a new exhaust section and secure it with appropriate gaskets and clamps.
