My MPE is ver 2 or 3 depending on how you look at it and I installed it myself and the install is perfect.

So bottom line, if it rattles you can look up underneath and you will find that most are not hitting the brace..... period

Those with ver 1 have suffered slippage with the style of clamp and interface it used but the sound is more of a metal to metal banging not a resonating vibration like these videos display...that is my point
Dude! Don't tell me or call me out for BS unless you know for yourself! I can tell you without exception in my case, and many others it is the exhaust slightly rubbing the bracket during cold start. If your tips are rattling, ok, that is the issue you had.

Edit: Ok, I am understanding the tip rattle better now and agree the videos are probably tips rattling vs hitting the bracket.
