I am curious about the pipe combinations for the .21? the pipe combo's listed are pco9382, 9383 and 9384.
The pco9382 has the 2033 which has been around for a while (and worked well on P7/8/9 evo2,3 motors) and is shown as a high rpm big track choice, while the 9383 has the 2120 which picco's website has listed as a more midrange pipe.

The 9384 combo has the 2116 which is not listed anywhere, is this a more low rpm pipe than the 2120 or does it fall somewhere between the 2033 and 2120?
