What is the thing next to the FPR? Its like a metal tube that comes up from the bottom and has a gray rubber plug on top, it also vibrates like crazy, no noise but I catch trails watching it.

Re: What is it?? (fluid72)

The other end connects to your downpipe/exhaust manifold. It is used by technicians at shops to stick sensors in there to tune/test the car. If you take the cap off, you will notice exhaust gases come out of it.
