"golf tee" trick

so i hear all about this but i cant find any instructions on how to do it. all i know is that you plug up a vacuum near your exhaust so that at lower RPM's (2500) you get a low grumble. I'm horrible at searching. i hear it most on E36 style BMW's. I think its only on BMW's though. its called the "golf tee" trick or mod.
