3" exhaust? 2.5" exhaust...??

Come on guys a little reading comprehension please. The original poster asked "Has anyone done and comparison of a 3" vs 2.5" exhaust on a mild stock stroke small block?" He asked based on a "mild, stock stroke small block. I stand by what I said and I'll defend it to the death. (quote from John Wayne's son in a movie) Any guess's?

2.5" is more than enough, and the benefit of weight/space/price savings over a 3" in this particular case is the best choice based on the current provided information.
