This is a pretty easy install.. I noticed a difference at first but I noticed more of a difference after the truck was driven a week after install...

Starts like this...

Remove the Plastic 6.6 Turbo Resonator starting with the torx screw in front... The purpose of this resonator was only to quiet down the turbo from the factory.

Loosen the bottom clamp on the resonator and twist it till its removed...

This is what you should see...

Here is the test plug that we will be using you can find it at Lowes for just under $4. This is a 2" Test Plug that has the metal plate at the bottom and top with the rubber grommet... As you tighten the wingnut it plugs the pipe... I also wanted to make sure that the wingnut wasnt going to back off so I got a 5/16 lock nut...

Here it is installed

Reverse instructions for re-installation of now useless plastic resonator... I did use some grease to get that thing back on easier since the top of the test plug was slightly wider!
