Need help deciding. I recently purchased off a friend a ****ty axle back system once I upgraded to berks high flow cats and upgraded y pipe the back pressure creates a canny rattling noise from all the air flow. Looking to replace the mufflers with a new set up and would love peoples opions. Currently on my car I have a takeda long tube intake, berks hfc, j2d y-pipe and ****ty mid pipe and axle back

I don’t think it is only reason because it’s not a raspy noise or move of a canny screeching noise when accelerating sounds coming from the back end I’ll try getting a clip later on
