what would be your #1 choice between these 4 slip ons

1. yoshimura
2.wb e-series
3.wb r-series
4.procircuit t-4

[Giz400ex]

none of the above!!

[400exdad]

Until I hear the sound of the FMF powercore4Q, my choice is stock. Of course if I get the Q, I'll have to start repacking! :mad:

None of the above, Curtis Sparks gets my vote

[400MXer]

Yup, curtis sparks or duncan double barrel. but i don't think Curtis makes a slip on, but duncan does.

Biggun for sure.
