Gilera FXR 180cc 2T Exhaust

[Delpzie]

Hello guys i wanted to make exhaust for my FXR 180cc 2T, but the problem is i dont have any dimensions, if anyone has dimensions from like the polini,malossi, jollymoto,pm tuning or pipe design exhausts it would be really appreciated. In any case i would need to design it my self

Thanks man but i already have seen that, and i know how to design the pipe accorddingly to my cylinder, i was asking if someone has dimensions of aftermarket exhausts it would be less time wasted for me.
