I can't seem to find a good answer... At 1000ish rpms in park and when coming up in speed (slow speeds) I get a vibration on my driver side floorboard. It's just for a second and then back to normal everyday front end sounds. Any thoughts? Thanks ahead of time!

I had a similar issue. Turned out to be the turboback exhaust would contact a crossmember, causing a vibration sound in the driver's floorboard. In Park, you could not see an actual contact with the crossmember when looking under it, but in drive, the drivetrain will move slightly and then would contact the crossmember, have someone you trust hold the brakes while you are under there.

Anything on this? Mind did it with stock exh, and I put MBRP exhuast and DP on and it still does it. Dont see anything around there underneath that would cause the vibration so not sure what it would be.
