Is this Magnaflow muffler legitimate?

I'm searching on Ebay and have found this cheap Magnaflow muffler. There aren't any customer reviews or clear descriptions on Google so I'm turning to here. 

I'm a little skeptical because this model number (100-1756) isn't on Magnaflow's website. It also says "replacement muffler" and not "high flow or chambered etc." Most of their mufflers start at $80 and this one is a fraction of that. 

Anyone know if I were to buy this, would it improve the sound like their regular lineup? Or is this some normal, stock sounding muffler?

This isn't a performance muffler. it's a quiet, stock replacement budget piece.

It's actually made by Bosal and marketed under the Magnaflow name through some outlets. It's not going to be any different from your stock muffler, and possibly worse quality since it isn't stainless steel. If yours doesn't need replacing, leave it alone until it does. Also, No one else wants to hear your car make more noise than it already does. You're no longer a teenager. Please grow up.
