Help fix drone issue
 

Hi all, I have fallowing set up: motor dyne V3 art pipes, tanabe Y pipe (without flex adapter), titanium top sicret mid pipe and muffler.
Set up sound good until 4500rpm above that have droning at 6000rpm sound like all hell got loose.

I have no problem changing Y pipe so
What you do think should I try? Will resonated Y pipe from Z1 help?
Custom resonated Y pipe? What type of resonators?



Will post video later today after back from the track
