The XDP (XD184 – Turbo Resonator Delete Plug) is a great addition for the 04.5-10 6.6L Duramax owners looking to clean up their engine bay by removing the factory turbo resonator. The XD184 will also give you the true turbo whistle vs what was being softened by the factory resonator. The XDP Turbo Resonator Delete Plug comes with a built-in O-ring for a simple install and perfect seal!
Step 1: Disconnect Batteries
Step 2: Locate your OE resonator under your hood.
Step 3: Remove all mounting screws/fasteners holding the resonator in place. Using a rocking motion, lift and remove the resonator plenum from the intake tube.
Step 4: Position the XDP Billet Turbo Resonator Delete Plug over the opening in your intake tube and press firmly using the palm of your hand to seat the plug into place.
