I really need help with this! It seems not modelling related but it is.
I've made a turbo for my supra. And I'm trashing the stock set up.
I'm just not sure yet on everything. I'm still not sure whether I should go for single turbo or Twin turbo. The single turbo looks easier to do but I'm still not sure. I have a few question for some of you guys.  I'm not really good at this kind of thing but I'd like to know what are those pipes behind the turbos leading to. In this set up it looks like the turbos don't have those pipes behind them. Do you guys think I should put those pipes or not. And this is the other option I'm going for.  If you can see those exhasut manifolds I have one question. I know that the tubo is placed on it. But my question is, the exhaust pipe us connected to the ends of those manifolds right? THX ahead of time. I've been trying to figure this out for two days now and so I turn to you guys. Please help me.

Those pipes lead to the exhaust pipe, and they should be there with the second setup as well, I think they're just not visible in the pic.

Just 2 more things I need to know.
What are those pipes called, and if those pipes lead to the exhaust pipe there is no pipe on the exhaust manifold that leads to the exhaust pipe, right? THX for the help so far guys. You're very quick, I didn't expect a response that quickly.

The turbo is driven by the exhaust gasses (see the link Sundicate posted for a complete explanation), the turbo is attached at the base of the manifold and then the pipe exiting the turbo continues with the exhaust.
The other pipe on the intake side of the turbo where the air is compressed goes to the intercooler and from there to the intake manifold. Ray

with a single turbo, you can make more HP (i think, cause alot of Supra people are converting their 2JZ's to 1JZ's)

What do you want your Supra to be? Fast, or quick? Twin turbo setups come from the factory because of driveability, the spool up quicker and can aid acceleration. A single turbo is usually much larger than each of the twin turbos, making it take a really long time to get up to speed, creating an enormous amount of turbo lag. This can be overcome to a degree with ball bearings and ceramic turbines and other fancy stuff, but any twin turbo, given as much attention, will be faster to spool up.
So if you Supra is all about max speed, go with one big honkin' turbo. If you want it to accelerate quickly, be it on the drag strip or the road course, give it two. That should be it, but correct me if I'm wrong, guys. I don't want to live in the dark, nor send anyone the wrong way.

Your partialy right will, lots of guys still keep the twin turbo setup, because you can get lots more horsepower, as well as lowend acceleration, and a high topend speed. this is achieved by using two different sizes of turbos, although the turbos may look the same size trust me there not. One turbo is smaller which is used for the acceleration, then the other is bigger for the topend portion.
