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!

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.
