850 SP big gun ecosystem exhaust help

Hey fellas. My big gun exhaust just came in the mail. It came with the quiet core for free and I put it in. Only problem is it seems to rattle.

What combination should they be put in the end?

It has a spark arrestor screen, spacer ring and the quiet core. Right now I have the quiet core and screen in and it rattles at the end. Big gun was nice enough to not send instructions so I’m not sure. I don’t want it to rattle when I install it.

I’ll post pics below of the 3 different items as well as the end cap.
