At what point is 3 inch exhaust required?
The thread title pretty much says it all, but in your opinion at what point is three inch exhaust neccesary? (as opposed to the 2 inch exaust I currently have).
I am sure there is a switch over point when it becomes neccesary when your engine goes over a certian amount of displacement or when you are running power adders (Turbo).
