I built the Mayko pipes for many years, tested most pipes of the day on the dyno, and I never say a difference in pipes between tracks.
We raced at Atwater, (huge long straight) down to Lodi, (a very short track) and used the same pipe, to some success, at all of them.
My Mayko Bullet pipe was very successful and the L2 RLV is very much like it.
Comments, compliments, criticisms and questions always welcome.
