[nathanhu]

well i finally recived the 57mm (999s pipes)system for my bike yesterday and went and fitted it before a few dyno runs

and 138bhp at the back wheel and 145 at the clutch. Thats a 5 bhp rise with just the exhaust fitted
not bad as im still using the origional 999r open cpu
im still waiting for the Fuel Adjuster to arrive .

does anybody else with a 04 999r have any power curves standard or non standard??
ill get mine next week and post them up

nathanhu... perhaps I am wrong, but that looks like the 54mm system.

[nathanhu]

what part of the system is 57mm or 54 mm ?
is it the manifold diameter

[nathanhu]

i used the adapter set for the 05 999s it only costs about €1300 ish

nathanhu - although I am not 100% certain, I was always under the impression that the 57mm system looks like this one here (accompanied by "twin" carbon heal guard):

and that the pics you posted above (where the pipe flattens down near the footpeg) is the 54mm system.
