## Abstract

A support for an exhaust stack comprises a first bracket including a first base joining a first extension and a second extension, the first base being fixed to the vehicle, and a second bracket including a second base joining a third extension and a fourth extension, the second base being fixed to the exhaust stack. A member is disposed between the first base and the second base. The member has a first end and a second end. A first fastener is accepted by the first end and extends between the first extension and the second extension. A second fastener is accepted by the second end and extends between the third extension and the fourth extension.

## Claims

### Claim 1

A support for an exhaust stack on a vehicle, the support comprising:
a first bracket including a first base joining a first extension and a second extension, the first base being fixed to the vehicle;
a second bracket including a second base joining a third extension and a fourth extension, the second base being fixed to the exhaust stack;
a member is disposed between the first base and the second base, the member has a first end and a second end;
a first fastener accepted by the first end and extending between the first extension and the second extension; and
a second fastener accepted by the second end and extending between the third extension and the fourth extension.

### Claim 2 (depends on 1)

The support as defined in claim 1 wherein the member comprises a flexible material.

### Claim 3 (depends on 2)
