So I can tell the difference between the hiss on decel, the normal rasp of non res pipe during accel, and the jitter from the flywheel on low RPM, but this rattle sound I cannot figure out. Any one experience anything similar? I'll try to get a video later.

I have berk hfc paired with m7 exhaust and I have the same rattle noise exactly between 2500-3000 rpms on decel only. It definitely sounds different than a normal hiss.

I think the issue may be from your berk product since we seem to have the same issue.

I'm going to have an exhaust shop take a look at my whole thing to see if there's any leak in the system.

My test pipes buzz the crap out of my Berk exhaust. I'm going to experiment with putting some dynamat on top of the Berk cans to try and change their resonance but I've not got around to that yet. If it fails I'm probably going to ng to have to pop on some resonated test pipes. (Ug! more weight)

I know exactly what you are talking about.

I had an Akrapovic for a month. Was great.
Got Motordyne ART pipes . And it was the worst thing ever.. 6 days later i sold the whole setup.

Apparently some exhausts dont pair well with test pipes or whatever.
Its not hiss what people claim, Its the disgusting rattle that sounds like you have drilled a hole in your exhaust.
