Vibrating Noise Behind Dash

[matt081288]

Hey guys,

I have a 2008 CC Powerstroke that now has an H&S Mini Maxx, S&B Intake, and 4"flopro exhaust kit on it. My issue is Ever since putting the intake on the truck I get this vibration noise,almost sounds like metal on metal or plastic on metal. It seems like it is coming from behind the dash right at the intake but I have pulled the intake and checked for places it would be rubbing and it is clear of everything. After I installed my full exhaust and my egr delete the vibration seemed to get louder and now it seems like it is coming from behind the entire dash. The noise only seems apparent when accelerating, and only becomes noticeable right before a gear change. Now I have put the stock airbox back on thinking that the S&B was the problem but the noise is still there. Please help me! This noise is driving me INSANE. Thanks for all yall's help.

Here is a video of the noise.

When mine was new I had several trips to the local shop to repair manufacturing defects. At some point the tech had pulled a clip holding insulation somewhere around the firewall and had forgotten to re-insert it. It made a hideous metal on metal scratching sound like fingernails on a chalkboard. They didn't show me where it was, just said it was a clip that held the insulation to the firewall. Hope this give you something to go on. 'Bout drove me nuts!
