if all mufflers flowed the same and sounded the same, why are there SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO many different companies, designs, shapes etc. Even between companies there are different designs to give customers a wide range of choice between quiet, throaty sound to loud, higher performance. Not to mention quality of material in the piping, and the packing of the muffler. Fujitsubu might be a strong gauge steel, might be lighter, I say might because I haven't dealt with either exhaust personally, I am just bringing up other arguments that back the argument of wanting to pay for high quality brand name parts.

Bottom line is, if you life by cheap parts (which is completely cool, cause God knows I'm paying the price for doing the same right now) don't try to mess up the sale of someone who chose the high road.
