Preventing Stress on Exhaust Hangers 

Challenge: Premature Failure of Exhaust Hangers & Isolators

Installing new exhaust components without neutralizing the entire system can place unnecessary strain on the hangers and isolators, causing premature component failure or excessive noise and vibration inside the vehicle.

Solution: Checklist for Taking the Stress Out of Hanging Exhaust

When installation of exhaust components is complete, be sure to check for any isolators with excessive tension. To alleviate this tension, follow these steps:

  1. With the vehicle and the exhaust at operating temperature, loosen all exhaust clamps and flange joints (if applicable). WARNING: Use caution; the exhaust system may be extremely hot.

2. Reposition any affected exhaust components until the isolators hang freely without excessive tension in either direction. For most slip-fit connections, the recommended pipe insertion is minimum of ¾" and maximum of 3". For flanged connections, closely inspect all body and exhaust hangers to ensure they are aligned properly.

3. Tighten all connections, starting from the front of the vehicle.

NOTE: With the exhaust secured and cooled, the rear hanger may be angled slightly forward due to length contraction of the system when cold.
