IMPORTANT NOTEHalfway through 2015, GMC made a production change in the connection between the catalytic converter and the turbo direct pipe on the LML. Please ensure you have the late LML 3-bolt style flange before ordering any of the kits listed on this page. If you have the newer 4-bolt flange instead, please refer to our 2017+ L5P exhaust sytems. |
