AFM: Currently, I am using an RD Logics Turbo II in-line pipe. Make sense using the Sirio In-line, wonder where I could get it. Overall, the engine perfomed flawlessly on my last race. The only thing I did to it was to replace the carb (used a Nova Rossi carb instead) and work the needle settings (Thanks to Maxy Velasco for helping me out!, I am looking foward to try your fuel)
I have an TP-04 somewhere in my toolbox, I will try it and let you know how it went.
Thanks!
