I posted this in perfromance too, so sorry for the duplication.

So I took off the large tube to the tuirbo inlet today. I wanbted to get a good look at the "baffles" and remove them. I was expecting something different I guess. Are we sure they are intended for sliencing? I almost think they are intended to straighten the air entering the last elbow into the turbo. That elbow has directing vanes in it, which leads me to beleive that these baffles are more to keep the air straight going into the elbow, rather than help silence the turbo.
