E90 M3 exhaust Leak?

So recently I added ACM test pipes to my car and all went well besides me not removing the stock cat bracket so I had a rattling noise at low rpm and idle. So this weekend I decided to take some time and remove the bracket and when doing so I re adjusted the clamp a little. Well today was the first time taking out the car and I notice this ticking noise and I can really only hear it well at low rpm when barley pressing the throttle or inbetween shifting gears as the rpm drops or when I turn my wheel like the video I took shows. Any thoughts on this? I notice the factory x-pipe didnt have a gasket but just figured it was normal as the rest of the exhaust just connects with clamps too. Thought... Comments would be appreciated.
