87 TII with a series 5 motor

i am wondering what i can do with the bottom BAC nipple that was connected to the compressor outlet on that "T" assembly (between the stock turbo and the stock inter-heater). should i plumb it into the new compressor outlet by having a alum. nipple welded onto the fmic piping? or should i just put a filter on it. i was told that the filter was ok, but also that the car wont idle right? what should i do?

I just run mine with a filter on it, however there is alot of noise from the intake pulses, if you don't want to hear it, plumb it back into the intercooler piping, I should also tell you though, that I am running a haltech with no airflow meter of course, so if you still have the airflow meter, it needs to see the air going to the Bac valve, or yeah it won't idle right..Max
