Yeah, I think I know what you are doing. Its what Im going to eventually do on my GTA. Magnaflow makes a system like this for 4th gen F cars. The Super 44 could be used the same way. You have the over axle pipe on the inlet side then 2 outlets on same side but one wraps back around the muffler to exit on the inlet side.
I want to use this Super 44 and have my exhaust guy build the system.
