You will not get a check engine light on a 96 without cats, but you can get the dreadfull IDLE HANG. My only mods were to take off the cats and run 3" from there back. Kept everything else STOCK and I got idle hang (no check engine light). I put the SIMMS on and it fixed the idle hang.

Roe as Plug and Play SIMMS.
