Mine is 3" its not so much a forced induction its more the power pulling and size of an engine. Turbos normally have a 4" turbo back for optimum performance. Most engines like the bseries engine would use 2.5" unless forced induction was added. There is not much difference between 2.5" and 3" however if wishing to go turbo or for most accord euros supercharge or increase the power substantially then a 3" exhaust will be a much better building block however there is nothing wrong with 2.5"
