I’m new to this site and hope i posted in the correct thread. I just bought a 2001 gt with the 4.6 and there is a pin slid into the obd slot that says silencer on it? I’m pretty sure it has a tune but not sure what the pin does? I can pull it out and am nervous about upcoming emissions testing. Any help understanding this would be appreciated.
