fmf pipe question..

[4cfed]

got the pipe i bought from braaap.. condition as explained and shown! anyway..
im confuesed its a fmf pipe but on the part of the pipe on the left side of the motor right where it turns over the top of the motor it says 'Riva Racing by FMF'

whats up with this pipe??? my pipe says 'fmf gold series' on the right side of the motor, they look almost simmaler as best i can compair half awake..

whats the diff between the 'riva racing' and my fatty?? ir any.. or is it just the naming??

i understand there both fmf just confused on the riva racing part

i belive thats what they had on there older pipes

i know the older pipes had the fmf stamping on the ride side under the tank like mine does.. and the newer pipes are on the left side, im just confuesed by the riva racing stamping, i emaield riva and fmf so hopefully i can figure something out

here are photos.. the one on the left is the gold serise fatty and the right one is the riva racing by fmf... which one would make more power??

 

[specialized7]

that one is quite a bit bigger, the other one almost looks like a sst

i think you might have them labeled backwards- but the one on the left should produce better bottom end gains as it's chamber is longer

nop there labled correctly.. and i lost alil bottom end with the riva BUT picke dup mid range and high rpm power!!! and the initial hit of the frotn side of the power band is harder
