Well not really the same as a tri Y.
The Idea of joining the two banks together with this Y pipe is
1. It fits the car. A 2 into 1 exhaust system fits this specific car much better.
2. to make the total system exhaust system scavedging a lot better. (more mid range torque)
The engine sees it as of the header primarys are longer than they are.
