this engine is not producing enough pressure to require anything larger than 2" diameter exhaust. i had a civic (130hp) with a 2.25 and shrunk it down to 2" and had noticeable gains.

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.
