rear bumper oddity
hey guys,
just curious if anyone has seen the rear bumper sag downward on the oem bumper w/out diffuser between the exhaust tips. I had exhaust installed over the weekend and when it was finished up there was no sagging problem, however, this morning as i was getting out to the car i noticed it looked like it was sagging. To best describe it, think if you have a piece of plastic and squeeze on each side it pushes the piece downward in a ͜͜ type of shape. wondering if maybe the exhaust settling in has put more pressure on the mounting brackets that are right behind the bumper or if the heat from the exhaust is softening the body panel so it appears to sag? anyone with any thoughts?

I've just recently noticed this on mine as well only mine does it more to the side towards one tip. Looks kind of bad and unsure how to fix. Did mess with the mounting point for the bumper and didn't help much.

I was thinking I would let the dealer fix it next time I'm in under warranty. I was thinking maybe I did it moving the exhaust around on a recent install of an xpipe.

do you think they will? my worry is that they will say it was caused by the install (even if it wasnt) and not fix it under warranty

Probably because I did the center section not the axle back which is still stock. I will just say I didn't even touch that how could it be related.

I think if we monkey around with the lower brackets enough should be able to fix it on our own. Or we could use this as an excuse to get a diffuser!

just went and laid under the car and looked for a few things - i think the exhaust having settled in has helped a few of the bolts to loosen allowing movement of the rear mounting bracket for the bumper. i moved a few things around and tightened the bolts as best i could without the car being on a jack and it seemed to help fix the "sag".
i will wait and see if it shifts again tomorrow and if it does ill get it up on a jack and see if i can tighten things down more tightly.
