DHD's high flow manifold bundle increases exhaust air flow over 55% without any port modifications. Additional gains can be found in port matching and port blending. Our manifolds are cast from the same high Silca Iron that's become standard in the high flow manifold market. Included in the high flow bundle are our .120" wall thickness 304 stainless steel up pipes, featuring sleeved bellows and double welded pipe/flange connections.
Our manifolds swept back tapered inner diameter port design will accelerate exhaust gases to the turbine, lowering EGTS and making it easier for the turbo to spool quickly.

Comments: Definitely noticed a big difference, especially in the middle of summer when it's almost 100 degrees out, truck spools a lot quicker than before. I love how the up pipes are stainless. Quality is awesome along with the hardware. 100% would recommend
