The RB V12 is similar to the NS but in my experience with it (limited 1 race meet!) it tunes a little easier, but lacks overall RPM compared to the NS. Appears to have a nice fat midrange.
As such I would recommend the RD logics pipe (turbo 2 style) (I have the THS branded ones, same thing) with the new shorter header. This will enhance the top end a little.
On a tuning note if you find that your RB is down a little on RPM add a .1mm shim into it and you will see a RPM increase.
