Please explain that to me.

As stated before, they are the exact same pipe, period. The only difference between them (besides the pretty endcap) is that the bb comes with an optional torque something-or-other insert that is similar to their quiet core.

Here is the catch. You probably know that the unrestricted HMF is obnixiously loud. So if you were to ride in any area where noise levels are a problem, a quiet core would be manditory. Because the torque insterter and the quiet core go into the same area you cannot run them at the same time. Now that you have the quiet core in you are back to the original HMF which you could've save $50 on.

Don't tell me that any of this info is false because it came right from the hands of the HMF guys on their forum.

yah,

so ur saying that the hmf is the same thing as the bb. and that you can get a quiet core for the hmf right?

[400exstud]

correct. The only thing that the bb has on the regular one is the torque thing and you can't even use that with the quiet core at the same time.

[quads14589]

how are the iron man series by hmf do they even make any for 400ex becuase i looked at the quiet race series and they dont say 400ex.

[quads14589]

the thing that is on the bb is called a torq mange modifier.

I have no idea how the TRM works...it must provide just a little back pressure at some exact point in the exhaust. I took my HMF sport end cap off to see what was inside it before I mounted it (I'm used to stock) and there aint very much there...you can see daylight through it...

It gives a lot of power though...
