It shouldn't throw a code if you where to do it after the rear 02' sensor, but if it is installed forward of the rear o2' it may throw a code and cause the engine to run rich.
I would strongly suggest NOT running open manifolds, it's unsafe because of the fumes and beyond obnoxious like said above! I had open long tube headers on my 87' Camaro for 2 days before I finished up the exhaust, and when you would start the engine you could literally feel it in the ground if you where standing beside it
