Get ready for black exhaust build-up on the rear bumper.
Sticking out, not so much black stuff on the bumper.
Taste over functionality any day....

POMBCHSTANG

No No, It's just in front of the rear bumper just like the stock one was. Before I had them cut they stuck way out like close to 3 inches, just plain ugly. So I squated down and looked at the lower part of the bumper, it's at an angle so just like I had done with the stock ones it came with and had them match that agle perfectly. My car is black and I never had any problems with the black dust before. But I wipe my car down in am just about every day. Labor of Love you might say. I proposed to my car yesterday. She said she would think about it! LOL.
