The TAG is available as shown and fits with the Dodge Cummins silencer ring in place. 

The Turbo Air Guide (TAG) is a new device invented by Diesel Power Products, which when used in the intake of a turbo charger can help to get more air smoothly in to the compressor.
The TAG straightens air flow into a laminar flow and directs it straight into the compressor of the turbo, resulting in more power, cleaner burning and better mileage.
The TAG 1 shown in the picture above is installed in the intake of a your turbo charger.
It is constructed of stainless steel welded honeycomb material.
