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.
