I vote for the underdrive pulley. It will also be lighter weight :-)

Some place to buy it online?

I decided to take the advice of a reputable and very good exhaust shop against the advice of some of the experienced YW members and I lost noticable torque. Had the shop re make a 2.25" and most of the torque came back and still has the increased top end.

That was with all the flow mods -dc header, MI intake manifold, intake, 1zz TB.

Good to know it.
