Since no input yet.. i went back under.

Hoping that everything has now settled with the new gaskets all around during the install, I went back down and retightened all the bolts from the cat to the back. Tightened the demon bolts down from the top. T handle clamps for the stillen intakes are a savior. Went for a drive. Vibrations still in the cross bar area for the midpipe.
I went ahead and removed the ARK midpipe and wrapped where it comes close to the bar. Snug fit but now it shouldnt be rattling metal on metal.
Startup sounds much more normal.
Park vibration is gone.
Parking with AC ON vibration is gone.
Reversing vibration is gone.

Driving has some vibrations in the throttle.
Completely stopped at a light in drive. The worst rattle/vibration than before!

Where else could it be hitting? I will usually just ignore it since my rear is gutted, but i have some free time
