Although the 77 looks nice and pretty, the dyno'ed performance gains tend to be higher on the standard kits.
The difference is the main tube material.
The plastic allows more design flexibility in wall thicknesses, among other things, and results, as I understand it, are generally superior than the metal tubes, in this application, as well as many applications.
The plastic tubes are also cheaper. So, seems like a lot of advantages, but maybe not as much "bling factor."
I don't know what either product costs.
