I thought the exhaust system had DP's with primary cats, then secondary cats followed by a resonator, followed by two mufflers?

I saw the Supersprint X pipe but that eliminates the resonator and I want to eliminate the two cats (or whatever they are) before the resonator but after the DP's. Might need a custom X pipe to achieve this as I can't find any existing ones.
