IMPORTANT NOTE: These kits will only fit models equipped with the OEM style 3-bolt flange off the turbo direct pipe! If you do not have a 3-bolt flange, please see our 2015+* Duramax Exhaust Kits.

The 3-Bolt flange has been a headache, this kit has been designed from front to back and fits like a glove.  “Turbo Direct” pipes in 3” to turn these kit into a true turbo back option will also be shipping soon.  All standard Flo~Pro Features to be included: Mandrel Bends, Preformed Band Clamps, and Welded On HD Hangers to mention a few…. The special sauce is in the flange, it’s been detailed!
