Exhaust system tech. Specs. for GT 2.0 JTS

Hello there!
I would like to ask for information on the technical specifications of the OEM exhaust system for a GT 2.0 JTS. Specifically I want to know about the central silencer after catalyst.
Like to know their measurements and diameters of inlet and outlet of the pipe.
I have installed a high flow one but my car lose power on high revs. Seems that the problem was compression because of the diameters of the inlet and outlet. Have installed one with 2.5 inches inlet and outlet and the problem was solved, but Im still trying to find a high flow one that meets OEM specs. in order to recover performance.
Thank a lot!
