exhaust question

What do you guys think of this? Trying to make sure what I plan to do will work, if I need anything else, if I'm overlooking anything, etc.

Right now I have an 01 GTP, and a 98 GTP. The 01 GTP has a stock exhaust, and the 98 GTP is straight piped, just a cat and 12"ish cherry bomb, welded all the way back, (very recently bought it this way).

I have a set of speed daddy headers with downpipe. I also found someone local selling a ZZP 3" catback (no res/no cat -zzp mufflers), a 2.5" catless/bungless DP(stock), a 3" catless/bungless DP(for catback).

My goal is to get the 98 to close to stock sound levels, it's stupid loud right now. I eventually want to install the speed daddys in my 01 GTP.
My thought is to pick up the zzp catback, install that in the 01, and then I will put my stock exhaust into the 98. Will the 01's exhaust bolt right into the 98 no problem? I'm not sure I'm ready to attempt the headers myself, so I might pick up the 3" DP as well for a temporary, so I can just get the catback in the 01 and put the stock into the 98.

Do you see any problems with doing this?
 


this is my GTP with stock mufflers, ZZP DP and thrush glasspack its hard to get these cars to sound good but its possible that's why i stayed with stock mufflers.

 
In my 01 if I put a 3" catless dp in, will I throw a code and be getting terrible mpg? Do I need to run an o2 emulator or something?
 
Yes u need an emulator. It fools ur pcm into thinkin u have a cat. Or get it tuned and make it think it doesn't exsist :)
