If you go dual fuel you have to give up your trunk for the CNG tank, otherwise it replaces the gas tank. Plus you can't tune the car optimally for either fuel. For best results pick one and tune the engine for that fuel.

Converting requires very little parts, but the advertisers make it sound like you need a bunch of new stuff or that you car needs to be built for CNG. You can see the same BS with regards to biodiesel.

Go to big-toys.net and check out the gas conversions, Franz will answer your questions.
