would a 90 gmc sierra exhaust fit on a 93 and pass smog inspection? (California)?

Well i used to have a 1990 gmc sierra with a 5.7L engine that i got large pipes, high flow cat, and a single chamber muffler that was able to pass smog with flying colors. But sadly that truck got totaled while it was parked outside my house, so i bought a 1993 gmc sierra of the same 5.7L size engine and the same truck length (regular cab, short bed).
Would my 1990 exhaust fit on my 1993 and still be able to pass the test visually? I mean, they should be the same but i just want to be sure that the cats would be in the same location.
