Pulse Air - Ford Pinto 2.0i
Another one of my dumb questions 
I´m gonna use the catalyst due to high fee here in Sweden.
So, Is the pulse-air "things" in the exhaustsystem necessary?
It makes it harder to design a exhaustsystem with them and the vacuum-"thing"

Not sure what you mean by a pulse air thing, but I used to own an RX 7 in the early 80's. It had a belt driven air pump that pumped air into the
exhaust to dilute the exhaust nasties to enable it to get through the Californian emission regulations. Seemed a bit of a con to me but perhaps
something like this would work for you?

I thought the theory is that it doesn't just dilute exhaust gasses it completes combustion/gasses react further in the hot exhaust.

Technical english isn´t my stronger side.
I´ll try to take a picture later.
But first I´ll try to explain.
There are 4 tubes attached to the exhaust manifolds.
I think they let air into the exhausts to make it cleaner before the lambda-sond (?)
So? Are they necessery?
