DMAX Diesel Max-Flow Performance Series Exhaust Manifolds | 2001-2016 GM Duramax 6.6L

Introducing The Max-Flow Diesel Log Style Manifolds. These Manifolds were built for those looking to utilize stock style up-pipes while increasing flow rates and decreasing EGT. Providing up to an incredible 27% increase (57% increase when paired with our High Flow Up-Pipes) in air flow over stock. The Performance Series Manifolds are made tough using high quality Ductile Silica Moly Cast Iron. The Manifold's ports are CNC machined to match the factory gaskets, this ensures 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 removing the down-pipe or the up-pipes.

Features:

• Reduced back pressure
• Better fuel economy
• Quicker spool up and lower EGTs
• 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 construction

Kit Includes:

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