did try the 2060(efra 2042)pipe today....
I am not so shore about the diference between this and my RB 2087.

But today i didnt do so much stupid overdriving.I think the 2060 have less in the top(not screeming so much) and seems smoother al the way with no lost of power...
This pipe defently fit my driving skils better.
It makes me more confident.
