When the car warms up and under boost the car has a rather loud growl? It sounds like it comming from right under the shifter or in that area. I looked for exhaust rattles, but couldn't find any. It's more of a deeper sound then that anyways.

Could this be the dual port wastegate or the test pipe? It doesn't do it a idle, only under boost.

Any ideas....thanks.
