It's difficult to do without the right equiptment to flow a nitrous system and to do it correctly. As a matter of fact not many guys are doing it. Most of the guys that are flowing there systems are doing it thru some of the nitrous experts in the industry. Guys like Jeff prock, Dave Koehler, the guys at speedtech, and there are many others. If you want to have a flowed system call one of the guys that do it every day. They can add the "tricks of the trade" into your system to make it work to its full potential. Plus you will have the added benefit of technical service after its all done. Its not too expensive either(usually around $400.00 for the service) Hope this helps.
