current vs HMF

[TacticalRedneckofKentucky]

i have a supertrapp slip-on on my 400ex. Guy said it would make most HP. Is that true?

Can yall be truthful-

what is the better pipe?

I DO like the tone of HMF better, had one on my 300ex, but heard them on 400exs' and they sound different.
Or is that just me?

Im looking for the loudest pipe out there FYI.. Dont like the supertrapp truthfully.. Horribal tone.

Not exactly sure how much power the S.T. makes but here is a link to our dyno charts for the 400EX. http://hmfracing.com/forums/showthread.php?t=57

These are honest numbers. The 400EX is what put HMF on the map. Its also the sound of an HMF on the 400EX that made me buy one way before I started here.
