Repair heat shield by finding exactly where the vibration is coming from, replace heat shield or repair by welding the lose part of the heat shield.

I had a rattle that continued to get worse as I reached approximately 2400-2600 RPMs no matter what gear I was in. This was more annoying than anything else. I had the local shop rip it off the bottom and no vibrations or noise since.

Exhaust heat sheild rattles once in a great while, but hasnt done it to much yet, butwill fix soon sometimes on those you only need to tightend something or bend something a little bit away from what its rattling against.
Rattling under my car... I found out it was a rattling heat shield, which I tightened with a worm screw clamp.

Noise in rear. Mitsubishi dealer thought it was muffler hitting trailer hitch. Only happens when I travel for some time so I believe that heat has something to deal with it.

Loud rattle noise coming from the heat shield. More noticeable when RPM's get higher between each gear. I tried clamps and exhaust wrap, but nothing would stop the rattle!
