vibration @ 2900rpm felt in floor???

[SicShelby09]

Im feeling a slight vibration at 2900ish rpm in every gear. I can feel it in the pedals and the drivers side floor. I can only feel it if Im slowly accelerating through the rpm range. And its not a total car vibration. Just in the floor and pedals. Anyone else feel this?? If its normal, then I will just leave it alone.

:shrug:

How so? Its very specific to RPM. I can reproduce it even in neutral sitting still. Just slow rev it, and the second it hits that rpm, I feel it. And if I hold it there, I can keep it vibrating.

motor mounts?

I had a similar issue when I put my stock mid pipe on, but like the other guy sadist could be motor mounts

My ORH pipe buzzes and rattles a couple times until the exhaust system warms up.

only going off of general car knowledge, not for this car, I'd put my vote as well on you found the resonant frequency of a motor mount.

Not with tune, and cat deletes.

[SicShelby09]

I'm lowered 3+ inches. Mine was doing this, buddy and I checked the driveshaft and the u-joint was done. Took the opportunity to get a 1 piece shaftmasters driveshaft and no more noise!
