2015 - 2016 Duramax LML
IMPORTANT NOTE
Halfway 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 the LP5 exhaust kits.
