I also confirm this statement.
My first one didn't last the weekend at the race school.
the second one that I got a year ago which was almost brand new, didn't last very long doing some street tuning. It was not as bad as the first one but its starting...
this was done with shorty headers and TP on the first one and the second one was using the PPE header.
I suspect the internal of the stock muffler cannot handle the increased flow/heat and has a very good chance to start rattling
