I can't say I've seen any really nice installs on a genIII or a gen II or I for that matter. Most people go other routes when looking to up the power levels. Your best bet is to broaden your horizons a little, go out into the world and look at some other cars and try to reproduce the look on the viper. That vette had one of the cleanest installs I've ever seen.
the job on your car reminds me of somthing I'd see on an 18 yr olds honda civic out at the late night illegal street races.
blue anodized and brass compression fittings with a little teflon tape/sealant - doesn't get much uglier than that but those twisted back straps come close. Anyway you should just try to get them out of sight...then it doesn't even matter what they look like.
I'd try to get ahold of the guy that did that vette and ask him where he got some some of the parts he used. His black hoses are a lot more stealthy than the regular steel braided hoses. Also his bottle mount with the built in heater was really nice as opposed to the NOS bottle warmer and the gold brakets.
