Berk muffler delete rattle or can like sound on WOT

Just got my Berk Muffler Delete installed on my N54 with stock mids and AR catless downpipes. Sounds bad-ass when cruising, however, under WOT it sounds rattly (like a can). The deep sound goes to poop (again only under WOT).

Made sure the exhaust is not touching anything and bolts are nice and tight.

Anyone else experience this?

It's a little hard to describe. Raspy sounds about right. The pitch on WOT isn't as deep and clean (as lets say 3-4k RPM). It's a high tone with a raspy hollow can-like sound.

I see you have catless dp
Do you also have catless mids?

If so then you will get some rasp.

Ahhhh-ha! Thanks man. Just wanted to make sure what I was hearing is the norm. I blew by a Cobra yesterday on WOT (for shitz-n-giggles) and when I heard the raspy noise, I sunk into the seat a little. The headless N54...lol.

Planning on Berk mids in the near future. Will this type of raspy sound progressively get worse?

Yeah, I was going to say the lack of cats and resonators is going to give the rasp. I kinda like the rasp tho. lol. I see you are in Miami, maybe I'll hear it one day.

Yea Berk Mids should cure it.

Also what you can do (what I plan on doing) is having some Vibrant 1792 resonators welded in the oem mid pipe where the cats are
