Can you post post a video of the noise?
is it more of a air screaming out of a leak whistle?
or more of an internal exhaust noise that’s like too open of an exhaust so I’m hearing extra internal noises type whistles?
is it more high pitches?
or more hollow?
and exhaust leak would sound like a rusted header

Any idea's what it could be?

If its an exhaust leak, give it a week or so then check all the connections for black carbon streaks which would indicate leaking exhaust. However the noise doesn't sound out of the ordinary for an aftermarket supercharged vehicle....pulley harmonics and blower noises is what that sounds like. Removing the stock cast iron manifolds may have opened the door for some harmonics.
No, but you have to undo all the clips and use some zip ties to clean it up
Thanks for the reply. It sounds awesome and pulls harder, but it's way too loud with the borla type s. I'll probably have to go back to the factory cat back.
