exhaust for 2fast

How about go 2F4R all the way. 2F4R exhaust and 2f4r intake manifold.
me and tiba is currently using the 2F4R Minarelli Exhaust. So far its doing a great job.

It is not said that the 2fast pipe from TRT is the best pipe. It depends on your whole setup. The 2fast pipe does it wel by me, but my own specs pipe frome JS does it 0,5hp better with a wider powerband
 
Looks? JS pipe looks all business

pipe

hi!
the js pipe is a dpr!i have the same in my old setup and my mind is that it's not really good on a 2 fast 80cc block(24.3hp...!) but only for 70cc mhr 7t.
Now i use the jollymoto pipe.
This advice is for minarelli, maybe for piaggio it's different..?
 
DPR and Jollymoto make both pipes on specs This is a DPR on JS specs and it has a lot more power than 24.3 hp. How long do you have the JS pipe? because it is possible that you have an other design of JS:W
 
Ye.. i've got one of the latest , waiting for my block to return from Karsemeijer as soon as its back we will test it also on 2fast piaggio then ill put some results in here
