your in the right place for help. These guys have helped me more than I can say. couple things though, if your pressed for time, having someone build it for you would be the best way-it costs, but...
if you take everyones advise on here, and build it yourself, it is going to take a lot of time, multiple builds, and lots of testing, but it will be cheaper.
I do 99% of my own work-I'm not what most would consider loud-so far only 151.xx, but everyday, i make improvements.
I've saved a ton of money doing it myself, but I've been working on the same ride for months.
just depends on what your situation is,
but i would for sure listen to these guys, they won't steer you wrong.
