Just recently installed the ARK grip exhaust. Absolutely love it. I noticed a few days later it would make a noticeable rattling noise on idle. I would also hear it when I would go over bumps. Going to get it checked next week. Im just trying to figure out with the case and wanted to see if anyone had the same issue. Possible leak? Or a hanger issue.
 
Hi EJ,

I also have an ARK GRiP exhaust and noticed vibration at specific rpms. It turns out the flex pipe on the driver side was rubbing against the frame. I took my car to an exhaust shop and they freed up enough space to where the flex pipe no longer touched the frame. Voila! No more vibration. Hope this helps!

Yeah EJ, I have an HKS exhaust similar to the Ark and had vibration/noise from the rear every time i put it in reverse. It was just a space issue easily fixed.
 
On mine it hit the front heat shield. I took it off and notched it out where the point of contact was. Problem solved.
