Has anyone actually taken one of our downpipes apart to see if there is a resonator that is curbing the turbo whistle. I am still in denial that this turbo can be this quiet. The fords have a resonator in thier downpipes, and they report getting really loud whistling when removed or changed for a new DP. *drool*

They don't have a resonator in them.

thanks

Take your air intake off - or replace it with and AFE stage II - then you can hear it http://www.dieselplace.com/forum/smileys/Approve.gif
