Fairly common and completely normal for Joe Z.

Agreed. Common with the JoeZ exhaust. Its because the JoeZ exhaust eliminates the secondary cats.

I can't speak for other members, but my stock exhaust did the same. It was very faint in volume but it was definitely there. Now I have the QES from ISS Forged and it definitely sounds loud! I love it!. My previous F did the same and it came straight piped. It's completely normal.
