Mine sits exactly the same way height wise as the OP which is in my opinion is too low. I have the stock diffuser and mine doesn't stick out past the bumper/diffuser nearly as much.

I adjusted mine by putting the rear on jack stands and supporting the muffler can with a floor jack then loosening the two exhaust clamps, moving the muffler into the position that I wanted and tightening the exhaust clamps again. I had to jack up the muffler quite a ways (almost hitting the bumper) when I was tightening the clamps to get it to max height because after you tighten the clamp and release the floor jack the hangar will sag under the weight of the muffler a bit.

You may want to ask your install shop where they cut the stock exhaust, there should be a dimple to indicate where to cut so you get the correct final length.

OP let me know if you need help.
