Thanks guys!

I got a chance to get under the car today. Took off the thin sheet metal shield and the bolts on the thicker black shield that holds the X-Pipe to the chassis were loose. Guess they came loose from vibrations or I didn't fully tighten them. Don't know. Put some lock tight on them and put it back together. Haven't taken it for a test drive yet but it sounded normal when I started it. Hopefully that was the issue ... if not will update the thread.
