Dynamax vs. Flowmaster?

[46stang]

the super turbos are similar to 3 chamber flows, ultra ss are stainless steel(real pretty)they are held together with a bead(like a reg. muff.) the last one is welded together like a flow. the insides are the same(ss & welded) as far as i know though. I think the last one is the loudest of the 3, but not positive.(welded)
p.s. the super turbo is not a flow through.
I think borla is flow through and maybe bassani, but can't remember. maybe some one else will?
