Introducing The Max-Flow Diesel Log Style Manifolds. These Manifolds were built for customers looking to utilize stock length 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. This kit includes Max-Flow Log Style Manifolds and 100% Brand New Up-Pipes with a Brand New EGR bellow. Some companies weld on 10+ year old used EGR bellows from used cores which do not last. Our Brand New EGR bellow is made out of 304 stainless steel which will not blow out like stock or even other aftermarket options.
