Max-Flow Full Flow Driver Side Exhaust Manifold

Fits 2001-2010 Silverado/Sierra 2500HD/3500HD

Part# MAX-FFM-0110

Our full flow manifold is pre-drilled for a 1/8" NPT bung which is perfect for your EGT or drive pressure sensor!

The Full Flow drivers side manifold is a must have upgrade for any Duramax owner. The factory driver side manifold is very restrictive due to the steering column relief. The Full Flow manifold does not have any restrictions so your motor will breath easier which helps turbo spool up and reduces EGT temps. 1/8" NPT bung is pre threaded so connecting an EGT or Drive pressure gauge is easy.


  • 1/8" NPT Bung
  • Improves Power
  • Direct Bolt in replacement
  • Lower EGT's
  • With both sides balanced now, your Duramax will run much smoother.
