whats with your bumper by the exhaust tip? looks bent in or something
Exhaust is too close to the left side and it ends up messing with the bumper and how it adjoins to the grey plastic piece.. I'm pretty sure thats it. Pipe needs to come out a little bit more and a little to the right. Then after a nice hot weather drive.. when the bumper isn't cold.. take a piece of duct tape and apply it to the underside of the section of the bumper that is bent/slanted.. Apply the tape underneath to the frame so that there is tension pulling up on the slanted section of the bumper ever so slightly, making it once again perpendicular with the ground..
Make sure the tape is covering a decent sized area of the underside of the bumper.. not just on the edge. Otherwise its putting too much stress on a small area.. Doesn't take long.. and don't forget to take the tape off..
I noticed mine starting to do this; it almost looked like the bumper was on wrong or the car was leaning to one side.. I then took a good 10 minutes to reflect on the cliche of using duct tape on a chevy. Oh well, it helped get the bumper back in line.. Shop that did my converter fucked up when putting the exhaust back on - among other things.
