Tr6060noise coming from transmission area

[GMCHRIS98]

Hello guys Im having this issure right now that I can’t figure out my 2014 camaro ss is making a noise like a exhaust leak rattle, at first I thought it was the header exhaust gasket but its not, I sort of hear like the noise is coming from the transmission by the clutch area it makes it at all time driving or in neutral with the clutch in or out,it has original luk clutch with 40k miles just had clutch slave replaced with a autozone one, the higher the rpm the more it makes it it also has a new pilot bearing oem too

you mentioned it happens driving or in neutral and clutch in or out and is engine rpm related. This strongly suggests it has nothing to do with the transmission. Clutch in or out suggests it has nothing to do with the clutch.

Is there a condition that changes or stops it? You mentioned engine rpm changes it, anything else?

It starts doing the noise louder as you put the rpms up sounds like a exhaust leak sound ill try uploading a video in a little, there’s nothing that stops the noise idling it still does the noise but very little, the car also has new ls7 lifters and rod and main bearings looked good when checked, it also has a LS Cathedral Port Cylinder Head to Rectangle Port adapters for the intake manifold im running a 5.3 on it for now with ls3 intake manifold

Even though you've checked the header exhaust gasket, other components of the exhaust system could be causing the noise. Check for loose or damaged components, including heat shields, exhaust hangers, and the exhaust pipe itself.
