Whole Exhaust System Question

[GSPI]

Ok, I've gone through and looked around a bit here for an actual 5.0 L exhaust system diagram of sorts so that I can understand the Mustangs' exhaust system from say 1986 and up (I understand that they are similar in design between 1986 through 1993). I found Walker's factory setup and I think this diagram is right:



Anybody have a decent diagram or photo of what the exhaust system is supposed to look like if the above diagram is not right? I understand too that people change these out and replace them with offroad pipes if they can or fix up the cats. I've found the recommendations on what is close to factory but I just saw an H-pipe configuration with 4 cats on it as well as one with only 2. I've also found a complete DynoMax system from offroad H-pipe to the Super Turbo Mufflers and the bright polished tips in a 2-1/2"diameter size.

What is right? Any suggestions?
