yes the y pipe goes where the headers would dump into the flowmaster resonators, so in place of the resonators he placed a 4 inch y pipe where the exhaust combines much like an h pipe or an x pipe and then it comes out into 2 2.5 inch pipes. the 4 inch pipe flows like a mother. I just dont sense any restriction on this setup over what I took off. I can tell the car just wants to rev and go effortlessly. It fits very nicely in the middle in the exhaust tunnel perfectly. I would have thought he would have used an x pipe but he said this would flow if not the same better. After the headers, flowmaster had two 2.5 inch pipes going into one opening in the resonator. It is at that point where the 4 inch pipe is welded and it shoots out to 2 2.5 inch duals straight out.

Miami muffler is the biggest custom exhaust business in south florida and probably the whole state of florida. They do semi's, race cars. etc.. anything with exhaust. all types of grade steels and solid aluminum exhaust also. He sells to other exhaust companies since he has a several mandrel pipe benders. He also sells on the internet as vrs exhaust for all types of cars. I am pleasantly surprised at the outcome.
