They all look the same unless you only plan on getting a muffler which will then vary. DC Sport is what's out there now that's a full Cat-Back system. I don't have one but the once I have seen look pretty good.
Yeah i saw that one on nico. its made by brmYea but that's only axe-back, only one that I know of that's a full Cat-Back is the DC Sport. Although I have seen on another forum a custom made cat-back with magnaflow.
