I have FMF PowerCore IV pipes on my 440 Ex's but I still have stock Headers. Should I kick up the money and get the FMF head pipes or will it make little difference since I already have the 440 kit? Also does any know if FMF makes a revlimiter for the 400EX?

 

do they make the power bomb for the 300ex??

 

The headpipe may or may not make a difference i really don't know. I would think so because the kit doesn't do anything for exhausting. FMF does make a rev limiter you can view it at www.fmfracing.com. hope this helps

Well of course it will help since its bigger. I don't know if it will help alot but it will be better. later
