Installed Cat Security for my Prius V

So I got this catalytic cover for $160 at:

You will need a rivet gun or give it to someone who has like a mechanic. I let my mechanic install it.

After driving it, I notice that it rattles. The bottom of the catalytic bangs on the cover only when I accelerate from a stop. The best solution I came up with was to crumple an aluminum/tin foil and wedge it firmly between the cat and the cover. I have had no issues for over a year now.
