I do have a cat, but the O2 sensor is before it.
I mainly run the cat so that the noise level drops. I can't be having every cop in the neighborhood pull me over for noise. Hopefully the new exhaust system smooths that out...
I guess I came to the conclusion that if you notice my dyno graph, the reason the torque drops off so suddenly is because my VTEC is set to kick in at 4000 rpm. I think it might be better if I just turn the VTEC off on the engine computer to continue getting torque. I might sacrifice more HP in the top end, but at least I'd have the torque to carry me through to it. Hmmm...
I really do need to get new cams to stop this "valve overlap" problem. Damn you Honda! You over-engineered again!
