Anybody else have this issue with the Invidia and know whats causing it?
I seem to be having the same issue with my Greddy SE exhaust. Your description is spot on to what I am experiencing...a rattle/grind noise that is brief but very noticable on downshifts and low throttle.

I think Econ may be right...makes sense. I just got it installed last Friday so I am hoping that the system just needs some time to settle completely. Just going to continue to monitor over the next couple weeks and see how it goes...
