Default loud metal noise under wot

today I stepped on it in first to about 3.5k rpm then shifted. But as soon as second was engaged, there was this metal noise that was parrelel to the motor firing. It sometimes does this when just steadily cruising down the street at 2.5k rpm in second.
my gues is an exhaust leak but could it be the motor even when it rarely does it?
also when it did it under hard acceleration, the car was not warmed up yet.
oh ya 2002 gt
