    I have got them from this auction site, they ship internationally:- https://www.jauce.com/

    Attachment 341633 Honda RS125 NF4 pipe. The header bolts up hard to the cylinder and the main body is held to the header with springs.

    The NF4 pipes are reasonably easy to fit. Mostly they just require a new header flange to bolt them to the cylinder.

    Attachment 341634 The later model NX4 pipe is lighter, more traditional type of racing pipe and has a much steeper header. Because of the header angle it is a bit harder to fit, but some cut and tuck will sort that.

    Both pipes work well, even on a low tuned engine and work better as the tune is improved. I have successfully used these pipes on my builds from when I started at 18hp to a best ever 32 hp.

    It is an interesting phenomenon that the same tuned length has suited both 18 and 32 hp but its easy to understand when you think about the exhaust heat and how it affects the tuned length.

    The same tuned length for lower hp and lower rpm == higher hp and higher rpm.
    Hi can someone give me the specs to make the rs125 chamber thanks
