rattle between shifts

[canadianbullitt]

Recently switched out my exhaust set up.
Went from stock manifolds with bassani x and borla stingers to mac long tubes off road prochamber and existing borla catback.
Now between revs and between shifts im hearing some rattling that wasnt there before. Cant really notice it while cruising. Seems to be just at revs and shifts higher than approximately 3k.
Any pointers?
Thanks

Kind of a mix between a rattle and the noise some of the other exhaust systems make as you cone off the exhaust after a rev. Might be normal for the prochamer but ive never noticed this on any video and I certainly dont like it.
