NSR125r exhaust restriction

[stirlinggaz]

hi,
i've srarted to dismantle a Honda NSR125R. In the hope i can tidy it up a bit, so it doesnt look as scruffy as it did when i got it.
i havnt done much riding on it, due to combination of bad weather & a couple of weeks in hospital.
so im unable to say what its top speed is etc.
anyway, i've taken off the exhaust (looks like oem honda & weighs an absulute ton!) with a view to removing the surface rust & coating it in VHT paint.
however, whilst im at it, i thought i'd look for any restrictions.

according to the info i've gleaned off interweb, if its restricted at engine end of exhaust, its done by a pipe inserted inside the "mounting stub" & its around 8 inches long.

mine DOES have a "pipe" but its only around 40mm.

can anyone confirm if this exhaust IS restricted or has the work already been done?

heres a link to what i'm talking about

It's hard to tell from the potato cam, if the inlet diameter is equal to the pipe further down then it is unrestricted.
