The pipe on it is a FMF Fatty # 160797  Y-28
Doing some research this it seems to fit yz250s from 93-4 & wr250s from 94-97

The silencer on it is a FMF Turbine sst # 020406 TDS-3
This seems to be for a 99-02 KX250.  It is def smaller diameter than a 500 silencer.

Is this exhaust setup a possible cause to my lack of power>>????

oh holy s**t   :-o:roll:... with this pipe and silencer of 250 it can not function properly as well.the 250 expansions chamber and also the diameter of the tube in the 250 muffler is too small for the 500 engine. i mean this exhaust is a performance killer. :evil:

 i use a modifyed cr500 stock pipe on my conversion. and it make my conversion a little bit oem-look  8-). and thats what kawasaki already a long time ago should build ... :wink:

 but you can use the body of the 250 muffler with the inner tube of a kx500 muffler and it bolts on right to the 250 subframe :-)

Jeez, sounds like the p/o did a hillbilly hack conversion. So not only do you have a 250cc pipe on a 500cc, you also have a kinked, restricted 250cc pipe on a 500. Sounds to me like you definitely found your issue..
