hmf exhaust

[racinred330ex]

i was wondering since the 250ex and 300ex are the same pretty much if i could buy a hmf full system for the 250ex and put it on my 300? also if this is possile would i lose any power beeing a 330ex not a 300/250ex:confused:

It won't work and the 300ex and 250ex are totally different maybe if you buy an exhaust for a 250x than it would work becuase there are almost the same but just with different features.
