Exhaust problem? No CEL

[Steve_Midnight]

2005.5 A4 Quattro 2.0L. Bone stock (that I know of).

So I was driving earlier and got my RPM to about 4,000-4,500 while in second gear. All of a sudden I hear a noise and immediately my exhaust was noticeably louder. The exhaust has remained loud and I notice a slight rattling sound when accelerating. No CEL came on. Any ideas or suggestions?

I can post a video tomorrow after work in the daylight if need be.

Potentially some play in the turbo?

Check your flex pipe and parts where the exhaust are bolted or clamped together.
