isn't horsepower a by-product of torque you kind of contradicted yourself and I agree with the drifting show, unless your running a turbo or an excessive amount of combustion pressure on an N/A car than 3 inches is too much on hondas that are stock or just have a few mods. Why do you think it sounds like that because its not being pushed out of the engine smoothly and cant push the combustion all the way through that size diameter pipe for that long of a distance P.S. it's called BACKPRESSURE so if you want to be a stereotypical Honda and be called a rice burner because you make that nasty fart noise, then cool get the 3 inch exhaust, but if you want to sound like your actually making power and actually feel that power than I would go with no more than a 2n1/2 inch exhaust until you are pushing forced induction.
