Introducing The Max-Flow Diesel Log Style Manifolds. These Manifolds were built for customers looking to utilize stock style Up Pipes while also increasing flow rates and decreasing EGT's.  
Providing up to an incredible 27% increase (57% increase when paired with our High Flow Up Pipes) in air flow over stock. These Manifolds are made tough using high quality Ductile Silica Moly Cast Iron. The Manifold ports are CNC machined to match the factory gaskets to ensure the highest exhaust flow possible. The Max-Flow Log Style Manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the down-pipe or the up-pipes.

Features / Benefits:

  • Reduced Back pressure
  • Better Fuel Economy
  • Quicker Spool Up and Lower EGT's
  • EGT Probe Port Pre-Molded and Tapped in each Manifold for Convenience and Increased Strength
  • Compatible with Factory Up-pipes
  • Eliminates the Flow Restricting Pinch of the Factory Manifold
  • Heavy Duty Cast Ductile Iron Constructions
  • Manifold Mounting Hardware is Included for a Hassle-free Install

Kit Includes:

  • Right and Left Max-Flow Log Style Manifolds
  • Manifold Install Hardware

​Optional:

    • Up-pipe gasket set (4 gaskets)
    • Engine Block to Manifold Gasket set (2 gaskets)
  • Add Max-Flow Up Pipes (Non-EGR)
    • Up-Pipes are made with .120" wall thickness 304 Stainless Steel and internally sleeved bellows for superior flow and strength.

    • High Quality Welds
