proformance wise which one is better just wondering

 

pro circut, just been my seat of the pants experiance..

 

FMF.

 

pc

 

that depends on the machine it's going on.

I had an fmf pipe on my 250R with a DG shorty silencer and I loved the bottom end it gave me. Screamed all the way through sixth. I also had an FMF ram valve, reeds, and .40 over piston. It gave a good grunt.

My brother has Pro Circuits on his banshee with .20 over pistons, 34mm Keihin carbs. That thing hauls. It runs a lot better now than when it had FMF pipes on it, but it also didn't have the carbs or rebuild.

It really depends on the machine and the condition it is in.

 

I think my PC generates a little more low end torque than my buddy who has an FMF on his 400ex. That's seat of the pants feel anyway. Could be tuning as well.

 

My opinion is that the PC is better.My friend has PC's on his banshee,and I've seen him beat alot of other piped banshees.
