Yes indeed the middle silencer looks not very happy with the extra flow. I'm not sure if a high flow catted downpipe will fix this issue. I guess there will be more people who tried this before on this forum.

I wanted a custom dual exhaust from the beginning. So when we found this issue we just changed out the middle silencer. But if you want to keep stock exhaust after the downpipe you should do some research.
