Well, I finally got my car to Performance Muffler here and had about 2 or 3 broken heatshield braces welded. She's rattle free now, and no longer drives me nuts at 2200 RPMs. Cost a $20.

I get the buzz at 1700 RPM. Pretty sure it's the double-sheilding on the front exhaust manifold. Found it when I was changing my oil. Was thinking about just drilling a hole and putting a rivet in it. But then found it even quicker to simply put one of those spring-steal paper clips on it.
