Unless you are looking for peak HP and drive often at wide open throttle you might want to consider a 4-2-1 system.
The one shown in that e-bay ad is a 4-1, which is good for improving top end horse power.The 4-2-1 improves low end torque, making the car feel more powerful moving off from a stop light, so it is better for day to day normal driving.

but how much is the hp gain??? I mean, I remember that somebody in old posts was unhappy with the hp that the 1zz can get in bolt ons. He said that with CAI, headers, muffler, etc, the 1zz just get a 20 hp gain in the wheels. Is this really true??? I know that the 1zz is not a racing machine like the B series of hondas, but I can't believe that with such upgrades the just get +20hp.
