If you want to reduce the movement, you can try what some have done and wrap a zip tie around the exhaust hanger. This will make it a little less compliant and move less. Circle the biscuit with a zip tie, and let us know if you like the difference in movement. I switched to an FSWERKS exhaust, and they have different hanger angles than OEM. This makes for a tighter exhaust that moves way less. I videotaped my exhaust and noticed that the FSWERKS moves way less than the OEM. The youtube link is in my build.
