titanium 4 for 400ex

[ti-ex]

does any one know how loud a titanium 4 with a power bomb
header would be

About the same as any white brothers or FmF. It would be a lot louder than stock, but then again pretty much all pipes are.

I have just the titanium-4 slip on with stock header and its definitely way louder than stock. It sounds very good too, a lot better sounding than the powercore IV. Its real deep and throaty. Not obnoxiously loud though.
