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.
Look for CodeRed's Versa Exhaust on youtube. He has a couple different ones. Lots of other versas too. I gotta ask around about the local legalities of using just one muffler ie. the resonator. Maybe that's an option for you?
yea i have the stillen axle back exhaust on the mr18 and i love it aswell i would suggest it ill get some pictures tomorow but it looks great and sounds awesome its got a mature sound to it but its still loud enough to put a smile on your face! it dosent sound like a rice burner thats forsure
