So far the OS P3, P6 and P7 (last one only for very very hot weather and long mains) have been working great, and last race tested the Mega Turbo 6 Hot and 6 Cold and they are very good choices too ...
For pipes, usually i race the torquey STS pipe and/or the Thunder Tiger Efra Legal 3 chamber long and short ones ...
