Os 105 hz r which pipe

[M333lws]

Hi I have a os 105 hz r .. would you run it with a os boost pipe or the mp7 as I have both

Thanks

From what ive seen at my club (and assisted with tuning) the Powerboost is doing just fine, no surprise really as it was designed for it. However I have no experience of the MP7, hopefully someone can give their findings or even better a back to back comparison between the 2. Was the MP7 originally designed for 90 size? or is there 2 versions the other being rated for the 105..
Incidently.. anyone got a used os91 fitting exhaust they may want to part with..im in need of one.

Or the Funtech 3DTE, nice sound, not as raspy as the power boost, cheaper and just as smooth
