Ive seen dynos on many different cars, and as a general rule, I look at how much power thw car is making , then decide what size pipe to use. I see with Civc's for example, that they work quite well with 2.5 inch, but only when u start getting into 400 plus hp, is it worth considering going any bigger. I'm sure the Focus is very similar where most people arn't looking for that much power, just a good gain over stock.
