if you both added a header and removed the cat there is no way you should loose any time you should be gaining good time.

I'm gunna go with Civic_Addict sell them and get the right one for the application. but even if they have larger primaries you should be getting an increase in performance.

my bet is that the lack of the second O2 sensor is screwing up your computer's reading's and there for screwing up the fuel delivery.
