Now having the BS in my car for 2 weeks and its my DD, I have noticed alittle bit of more vibration but nothing to serioous that it doesnt worry me. In the 2000 to 3000 rpm range when accelerating slow you can feel it alittle. When crusing or WOT in between those RPMs its fine. When idleing you can feel it sometimes if your feeling/listing to the vibrations.
Its a $30 mod that gets rid of atleast 15 pounds. Why not.
