RE: Pro Circuit Pipes
kdxtrailrider,
First a little bash for the fmf pipes: if you've checked out all the threads, then you've read about the fmf pipes rubbing on the rear spring, causing a nasty little squeaking noise. Easy to fix, but I haven't heard of Procircuit pipes having this problem in the first place. Makes you wonder about the build quality between the two brands. :p
Don't get me wrong, I like fmf. But an fmf pipe is not worth getting rid of your perfectly good Procircuit pipe for. Procircuit's KDX pipe runs basically like the fmf rev pipe. Like I, and many others, have said before, if you want more low end (out of ANY pipe), just add a spacer (pipe seal) between the pipe and cylinder. Again, I did this, and it gave my Procircuit pipe allot more grunt, and it still revs like crazy. And if you are satisfied with what you have, why risk a change.
Back to the dents and rust... If you have a "platinum" pipe, rust isn't an issue. Only the "works" pipes rust, because they are unfinished. Regardless, the rust that forms on the "works" pipe is only a slight surface rust, and the rust on mine usually gets rubbed off when I ride anyway. The fact that the works pipes are unfinished also makes them cheaper to buy than the "platinum" pipes. Other than the finish, the works and platinum pipes are the same. The PC platinum pipes have a similar finish to fmf pipes, and don't get rusty. As far as dents are concerned, I don't have a pipe guard on my bike, and my pipe hasn't been bashed in yet. Neither the fmf or PC pipes are as indestructable as the stock pipe, and I think it would be equally easy to smash either one (except for the heavy duty fmf pipe).
Plus, as a side note: As you noticed, most of the guys with aftermarket pipes have fmf. With a bike as common as the KDX, I think it is nice to have one that is a little different than the rest...wait, on second thought, get an fmf pipe lol! :D
If I ever have to replace my pipe, I'll get another Procircuit, (call it brand loyalty, like all the folks who swear by the KDX). I hope this helps you make your decision.
