    I’ll have to check the rear block off plate.

    When I installed the kit I lost the original plug and bought a new one that didn't seem to fit great but I snugged it down anyway.
    I don’t run the plug I have the egt probe in there but the squeal I had was real loud and sounded like it was coming from under the dash. It still whistles with the straight pipe.

    Mine has that squeal with the EGR cooler in place.

    I started to hear it as soon as I went to a 5” straight.

    I’m gonna guess there is a leak at the brake/ down pipe flange.
