OS Speed, the best is it save fuel so much even compared to 2630. but top end losses some power.
T. Shimo, overall was satisfactory, the reason for buying this pipe is because its stinger is only 5mm, which i assume plenty of back pressure. i still prefer this pipe over OS Speed, since T. Shimo is a little bit cheaper.
I must say the OS pipe did not work for me. Tried changing setting so much because I seem it works on OS but gave up after 3 tanks.
Anyone interested to try HEC pipe, let me know. The prototype I tested should be out in about 2 to 3 weeks so need to order now or contact Harmony. Not selling here, just want to share what I think works.
