Abstract
An exhaust treatment system includes an exhaust treatment device having a stepped outer diameter. First and second clamps each include a stepped inner diameter such that the clamps engage the exhaust treatment device and other portions of the exhaust treatment system when the exhaust treatment device is properly oriented. The exhaust treatment device interferes with one of the clamps to preclude coupling the exhaust treatment device to an adjacent portion of the exhaust treatment system when an attempt is made to install the exhaust treatment device in a reversed improper orientation. A consistent exhaust flow direction through an exhaust treatment device such as a diesel particulate filter may be maintained through use of the inventive system.
