    hmf or powercore 4 answers plz..

    I think i am gunna go with the fmf powercore 4 slip on and eventually get a head pipe after i get some money or i will go for a white brothers e-series exuast slip on. I cant decide. Do any of u got any suggestions or any other pipe recommendations? I like the tuneable exaust but it might be a pain. The powercore gives power and more torque through out the entire power curve...the e-series is adjustible... it is a little more expensive though. any other pipe recommendations?

    i read....

    i read an article about hmf and it says it produces a nice gain on the botttom end for horsepower and tourqe but on the top end the gains were"quite small".... is this right? they also placed the fmf powercore 4 right next to the hmf for power except they said the powercore 4 showed a steady horsepower increase from bottom to top end. unlike the hmf which is mainly bottom.. ?? anyone have any help on this subject?
