Exhaust Bellows VTAD

Exhaust bellows are designed and used to absorb vibration and the thermal expansion of the engine. The bellows, the flexible part of the expansion joint, is a multi-layer construction with thin layers of heat resistant stainless steel. This is a double bellow, therefore longer than a singel bellow.
