Yah, definitely do something about the exhaust. Does look rather strange with the gap.
As for the bumper paint color... I dunno man, it doesn't look right to me. Not very color matched.

Here is the pic of the front of the vehicle. Most of the pics I have seen on this forum of the rear m5 bumper do not have a rear mesh insert. Is there a place I can purchase a mesh insert. I will be going back to the shop to have them install the dual oval tips. As for the paint match the glare from the sun may have given you the perception of not being color matched well. I have found these tips on ebay which I think will fill the exhaust cut outs.

I had PDC issues last year with the Umnitza M5 rear. The hole in the bumper wasn't as issue in my case. The sensor would fit but all the readings would be flatlined like i'm about to hit something. At first I thought it might be reading the edge of the holes. This was NOT the case at all. These BMW sensors do have a left and right if that makes sense. They must go in, in a particular way. Umnitza's PDC brackets that hold the sensor are turned 45 degrees causing the sensors to instead read left and right, read up and down. the sensors are then reading the ground which causes it to give that "false reading". What I had to do was cut off the two tabs that hold the sensor to the bumper. I then rotated the sensor to the correct position and used so epoxy to keep them there. The flaw in this resolution is if I were the change bumpers I don't think i could remove my PDCs from the Umnitza M5 rear. Major design flaw in Umnitza's M5 PDC rear
All of this makes me glad I didn't order the rear. I love the front (and it went on smooth), but the rear looks like a PIA to get right with PDC's. The last thing I want to do is make multiple trips back to the auto shop. I hate going to them as it is.
