The heat shield that is the farthest back by the tailpipe has come lose. I tried to zip tie it up but it seems like that is coming lose slowly. Any other options? Can I use self taping screws to go back into the frame? Or what else would work?
Those held in place by nut on the stud and sometimes aluminum shield corrode out around the nut. Put some PB Blaster on the stud, remove the nut, put a fender washer and the nut back on the stud to hold the shield back in place.
