Yes i can get that noise when i rev the engine when parked an keep it steady at around 2000 rpm.
the catalyst is changed for 2 years ago but can be broken anyway.
have tried and listn around but it is verry hard to hear where is coming from.
will check the catalyst when i come home again.
Many says it has to be the valve lifters but i think is not when the noise come only on a spesific rpm ?
