i have this rattling noise coming from my exhaust. i have a mac prochamber with flow 40 series. the rattle happens and idle and throughout acceleration. I put pressure on the midpipe with a pole at idle and it went away. all bolts are tightened and secure. any ideas of what it could be? its really annoying and pissing me off. I also feel a loss of power. All info is appreciated

check for leaks

and check for contact... I had an issue with the X pipe making frame contact till i bent the pipe slightly for clearance
