HMF or FMF

[Blown97Stang]

05 400ex I have a power bomb header undecided on pipe narrowed it down to either FMF powercore IV or HMF Ironman what do you guys think.

HMF, also people are gunna say Sparks and Yosh.

I would go HMF though

[procircuit406ex]

Sparks, HMF, or Procircuit would be my top 3 choices.

HMF's sounds sweet!

[jrm03]

Had the Powercore, and now I am pleased with the HMF

[exrider008]

i love my HMF!

[400exrebel09]

I'd go HMF. by the way anyone got one for sale for a 400ex?

[wheeltrax]

ill throw another vote towards HMF. Great quality, and if you get the PC'ed silencer they look awesome.

ON a side note what series HMF is everyone running i see a few models fit.

would there be any problems in bolting a hmf pipe onto a big gun head pipe
