I'm installing an Evo on my Aerox engine, which I will run untuned. I currently have OKO 24mm, Malossi overrange and so on. My current pipe is a Yasuni C16 which pulls very hard in the upper 11's thru 12's, and is happy in the 13's. Usually the C20 is recommended for the Evo, but my C16 is paid for. Is there such a big difference in performance?
