I think that's what I will do as well. I didn't have a chance to remove my headers and inspect it the other day.
I did change the spark plugs. No noticeable difference. I did realize that my turbo is leaking on the backplate near the intake(oil on it). I'll be getting it checked out this week. What headers is everyone running who is having issues?

As for rasp, don't waste your time with anything other than a Q300 or some other suitcase muffler, or a turbo.... front and mid pipe make very little difference when running a catless header. I went down that road already and tried several combinations of front pipes and cat backs. Only thing that tamed the rasp was a Q300 catback. A turbo will tame it as well.

That was my old set up running now FA20 header and a custom 3" turbo back.
