[B]FMF or Pro Circuit[/B]

[macholda_yz]

I am looking for the best pipe and silencer combinations I can stick on my 2004 YZ-125. I have experience with FMF on my previous bike but have also heard good things about Pro Circuit. With the FMF line it would be between the Fatty or SST pipe and the Shorty or Titanium 2 silencer. With the Pro Circuit like it would be between the Works or Platinum pipe and the R-304 silencer. Please help me out, thanks.

If all you're doing is adding a pipe, then just pick one. You won't be able to tell that much difference from stock. Yes, the pipe and silencer will make some difference, but you could get a more noticeable effect by changing your rear sprocket. If you were going to have cylinder and head work done, then the pipe and silencer would be a must. Either way, I would recommend Pro Circuit.
