Stainless Steel Performance Manifolds FOR 2001-2016 Chevy GMC Duramax Diesel

 

PRODUCT DETAILS

****These Exhaust Manifolds will ONLY work with OEM length up pipes****

Providing up to an incredible 55% increase in air flow over stock. These Manifolds are made tough using high quality 304 Polished Stainless Steel.

The High Flow Manifold has been meticulously designed to increase the engines output through increased airflow. High Flow manifolds are designed to have a gradual increase in internal diameter as more exhaust ports are added. This allows for added volume within the manifold while keeping the maximum velocity possible. Due to the heat and energy of the exhaust gasses being expelled, expansion will occur within the Manifolds and Up Pipes which can cause an even stronger spool up through the Turbine side of the Turbo. With an increasing diameter of the Manifold you will be able to send these hot exhaust gasses through the turbine as fast as possible making it easier for the Turbo to spool. The material also has the ability to retain heat ensuring the heat stays within the Manifolds. Better spool times have been seen with these Manifolds over Aftermarket Headers because the Headers will actually increase the distance the gases needed to travel causing some cooling before the exhaust gases hit the Turbo Charger.
