what would be better for my 300ex, an hmf pipe or an fmf powercore 4?

 

neither, i think White Brothers would be better than both.

 

what are the benefits in getting white bros. over hmf or fmf?

 

Im pretty sure the HP gains is better overall than the 2 listed. Plus, White Bros pipes are popular among EX's.

 

HMF doesnt have a significant track record with honda aside from the 450R. FMF pipes are typically middle of the road at best. White bros has been one of the few companies that has shown great interest and great performance in the honda four stroke line. They have more r and d money into honda than most manufacturers and their products reflect it.

 

alright, thanks

 

I had the PowerCore 4 on our 300, and it was great! BUT, more important is the HEADER!!! That stock header is TINY and very RESTRICTIVE. Loose it ASAP. I highly recommend the FMF PowerBomb header!

 

i would get the hmf. the quality seems to be great. also, the e-series pipes almost all break if you race. they just seem to crack easily, even the new ones that were reinforced. you would get good power gains out of the e-series though. i don't think it will surpass hmf though.

 

Cals400 is right they do break if you race them but id go with the HMF i think is better looking and better sounding than the White Brothers E series also it the e series might make more power but id rather have something that stays together instead of breaks

 

HMFs sound way better than a WB. But, if you want the most power, I really can't answer that question. I do know that WB was the best a LONG time ago. Don't know about now, many pipes have come out since then.
