Have you ever driven a Mustang with an aftermarket shifter (Pro 5.0, Steeda Tri-ax, ect)? Those cars have noticable vibration and gear whine akin to a FIA rally car. I just installed my B&M today in the 240 and it is nothing short of awesome. The OBX is a flaming pile of crap that I wouldn't reccomend to my worst enemy. It moved up and down, caused missed shifts and spun around like a top. The cup at the bottom had disintigrated and transmission fluid flew out of the top like a fountain. I would have rather had a stock shifter over the OBX pile.

I took Jeff240sx for a ride in it and he didn't notice any whine...and I had the center console out with just the dust boot covering the shifter mechanism itself.

Different strokes for different folks I suppose.
