- Flexible bellows section absorbs vibration and thermal expansion.
- Maintains a sealed exhaust path between the engine and downstream exhaust system.
- Designed for high-temperature heavy-duty diesel exhaust service.

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

The 4077078C3 transfers hot exhaust gas from the turbocharger into the downstream exhaust system while allowing controlled movement between rigid exhaust components. The bellows section helps prevent engine vibration and heat expansion from being transferred directly into adjoining exhaust components.

Issue Symptoms / When to Replace

- Exhaust leak or soot around the bellows or welded joints.
- Louder exhaust noise near the engine or turbo outlet.
- Cracked, split, or distorted flexible bellows.
- Exhaust odor caused by leakage ahead of the downstream exhaust system.

Installation Notes

Inspect the mating flanges and support points before installation; damaged alignment or exhaust supports can place excessive stress on the replacement bellows.

How to Identify an OEM Part

Verify 4077078C3 using the International/Navistar identification label or permanent part-number marking on the exhaust assembly.
