If your potential buy has had the resonators and AIV's deleted as well as the rest of the typical Z32 power exhaust mods, you will need to replace the entire exhaust to meet emissions or have those parts re-added to the current exhaust. Difficult since it is 3", so you'd have to source OEM output-level components to fit 3" which may or may not exist.
Bottom line is that if you live in an tight emissions state as I also do (Washington), you need to run a full exhaust.
But, unlike current thinking most everywhere that says you need 3" pipes, no guts, etc., you CAN run a full exhaust and get good sound, AND good power! It's all just marketing BS and people enjoying race cars...a quality mechanic will know just what to do to make solid power and not be overly loud, or modified too far beyond stock.
I have 400+ hp and upgraded most everything under the hood and running on aftermarket ECU, and am running on stock exhaust with only two exceptions- upgraded DP's for the upgraded turbos (necessary), and a 2 1/2" tailpipe and muffler combo spliced into a aftermarket old Z32 catback setup. It sounds just awesome, spools correctly, and just a tad louder than stock unless we have the pedal over halfway. SUPER cheap as well compared to the aftermarket items! NO drone as is common with 3" exhausts as well, my biggest issue with the current exhaust thinking.
EDIT- Oh, and it DOES pass emissions BTW.
Hope this helps!
